5.1.2. Functional Description

The receiver is mainly composed of RF chipset and Front-end Module. The RF chipset for the Dual-band receiver is the Transceiver IC U101 (PMB6256VV1.1) integrated a direct conversion receiver with DC offset calibration circuitry. The PMB6256 contains the following circuit blocks.

8 EGSM900 and DCS1800 internal LNAs. 8 EGSM900 and DCS1800 down-conversion mixers/demodulators. 8 Channel filtering and base-band signal variable gain amplifiers with programmable gain control function.

The Antenna Switch Module S101 (LMSP54AA-117) is a dual-band antenna switch module. Two external SAW filters EL201 and FL202 (B7820 and B7821) for EGSM900 and DCS1800 are used to improve the isolation between 900MHz and 1800MHz. The impedance of these two filters' output is 150 Ω balanced.

EGSM900/DCS1800

The input receiving signals into the LNAs coming from the SAWs provide out-band reflection. However, the receiver is a direct conversion type, there is no need to concern about the image frequency blocking problem.

– 5–2 –

■ Transmitter Description

The main block for the dual-band transmitter is also the Transceiver IC U101 (PMB6256V V1.1) RF chipset. The Transceiver IC U101 (PMB6256V V1.1)'s modulator is a direct-conversion architecture, so there are no Tx IF frequencies. The Transceiver IC U101 (PMB6256V V1.1) contains the following Tx blocks:

8 Dual-band (EGSM900/DCS1800) IQ modulators with outputs at final frequencies, and integrated IQ uplink low pass filters. 8 Open collector outputs to the rest of the Tx chains.

The open collector outputs of the Transceiver IC U101 (PMB6256V V1.1) built up with two differential circuits, so called H3 filter, are led to the Tx Limitter IC U102 (PMB2256 (Lumpi))'s dual-band amplifier/limiter. The Tx Limitter IC U102 (PMB2256V V1.1)'s limiting function helps to reduce the AM ripple coming from the IQ modulators. The 900 MHz output signal from the Tx Limitter IC U102 (PMB2256V V1.1) must pass through a Tx SAW filter FL102 (EFCH897MMTE7) before entering into the PA Module U103 (RF3140) in order to ensure Tx noise in Rx-band satisfy GSM specifications. For 1800 MHz, the 11.10 specifications are not very severe, so no SAW filtering is needed here. The signals are then attenuated through two attenuators to meet the drive levels of the PA Module U103 (RF3140). Power control is managed through the control line PALEVEL. Harmonics coming from this PA will also be removed inside the Front-End Module.

■ Synthesizer Description

The EB-X60's synthesizer is included in The transceiver IC U101 (PMB6256V V1.1). The internal VCO operates from 3.42 GHz to 3.98 GHz, thus it is equivalent to 2 and 4 times of the DCS and EGSM frequencies. The registers, counters and phase detectors for this synthesizer are included in The transceiver IC U101 (PMB6256V V1.1). To meet GPRS's lock-up timing, the Transceiver IC U101 (PMB6256V V1.1) is included a switched frac-N and integer-N counter. Also, it is included the facility for the switched bandwidth loop filter. The TCXO module U301 (MAA3259A) generates 26 MHz in order to provide the reference clock to the transceiver IC and base-band portion. As generated signal's frequency is changed by temperature, AFC functionality that base-band IC provides control voltage and keeps frequency within a certain range is supported.

■ MCU (C166S)

The C166S controller core combines advantages of both RISC and CISC processors in advanced architecture which closely couples on-chip memory and controller peripherals to the core in a very efficient way. This micro controller works in 32 bits or 16 bits instructions and on 32,16 or 8 bit data. The C166S architecture is based on RISC. The core uses multiple variable register banks, and single cycle context switch support. The memory space us organised logically as a van Neumann architecture, but physically the core uses multiple high bandwidth buses and core memory to increase performance.

■ Memory interface

The U2001 E-Gold + V3 has a physical address space of 128-Mbit / 16-Mbyte. The actual amount of memory needed depends on the features included in the product. The number of features also has an influence on the required memory access speed. The memory data bus is 16 bit wide. The SRAM utilizes the BHEQ signal to support both 8 and 16 bits access for more efficient use. The memory interface of the U2001 E-Gold + V3 supports 1.8 V or 2.6 V operation, allowing flexibility on the choice memory components. EB-X60 adopted 2.6 V operation because the operation voltage of memory is 3.0 V operation. The memory interface voltage level is selected by connecting the VDD2.0x supplies on E-Gold + to either V_SD or to VINT.

■ Clock Interface

The U2001 E-Gold + V3 clock generation unit is used to generate all major system clocks. There are two clock signals connected to the clock generation unit.

8 32 kHz clock F32K 8 26 MHz clock F13/26M

The 32 kHz oscillator is used for the Real Time Clock block. As a power-saving feature the 32 kHz clock can be also used for the MCU domain. The 32 kHz oscillator and the RTC block have its own power supply pads. It has the facility for a back-up power source for when the main battery, etc. when the main battery is discharged or temporarily removed. The 26 MHz clock is used as the major U2001 E-Gold + V3 clock reference. An on chip shaper is used to maintain the low-swing input level on F13/26M. It can be powered-up with a delay (programmable in ECO block) related to the TCXO power-up. This can slightly reduce overall power consumption.

■ Interrupt and Exception Handler

An Interrupt and Exception Handler is responsible for managing all system and core exceptions. There are four different kinds of exceptions that are executed in a similar way:

8 Interrupts generated by the Interrupt Controller (ITC) 8 DMA transfers issued by the Peripheral Event Controller (PEC). 8 Software traps caused by the TRAP instruction 8 Hardware traps issued by faults or specific system states

Normal Interrupt Processing

The CPU temporarily suspends the current program execution and branches to an Interrupt Service Routine (ISR) in order to service an interrupt-requesting device. The current program status [Instruction Pointer (IP), Processor Status Word (PSW), and in segmentation mode, the Code Segment Pointer (CSP)] is saved on the internal system stack. A prioritization scheme with 16 priority levels and with 8 sub-levels (8 group levels) specifies the order of multiple interrupt-request handling. The maximum number of interrupt requests supported by the core architecture is 112 (configured in steps of 16).

Software and Hardware Traps

Trap functions are activated in response to special conditions that occur during the execution of instructions. A trap can also be caused externally by the Non-Maskable Interrupt (NMI) pin. Several hardware trap functions are provided for handling erroneous conditions and exceptions that arise during the program execution. Hardware traps always have highest priority and cause immediate system reaction. The software trap function is invoked by the TRAP instruction, which generates a software interrupt for a specified interrupt vector. For all types of traps, the current program status is saved in the system stack.

Interrupt Processing via the Peripheral Event Controller

A faster alternative to normal interrupt processing is servicing an interrupt requesting device by the C166S's integrated PEC. Triggered by an interrupt request, the PEC performs a single-word or byte data transfer between any two memory locations through one of 16 programmable PEC service channels. During a PEC transfer, the normal program execution of the CPU is halted. No internal program status information needs to be saved. The same prioritization scheme is used for PEC service as for normal interrupt processing.

■ General Purpose I/O

The MCU can configure the pin functionality of most of the pins after reset. Whether those pins show GPIO functionality or one of the alternate functions ALT0 or ALT1 is defined by the PxCONF and PxALTSEL registers. Because some of input functions appear on more than one pin, the PINSEL register must specify the respective pin. In case of ASCx the active input needs to be set by the SxPISEL register of ASCx. For peripherals which are not able to select or disable their input signal, the corresponding input signal must be enabled by the INPEN register.

■ Specific I/O

Specific I/Os are reserved for the buzzer and keyboard. Buzzer is not supported in EB-X60 because ringing tones are sounded through a speaker.

9 PWM

The U2001 E-Gold + V3 supports driving a ringer with a digital PWM signal RINGIN. Earpiece buffer one can be switched into ringer mode by setting bit RINGSEL in the voiceband part of the analog control register. The input to RINGIN can be selected by setting the bits RINS0 and RINS1 in the voiceband control register. The ringer input signal is usually a pulse-width modulated signal which can be programmed conveniently.

9 Keypad Interface

The Keypad gives a 6 x 4 scan matrix allowing 24 keys. The keyboard interface provides a passive key detect function, where a key press can be detected without activity scanning the matrix, thus enabling a fast key response, even when the CPU is in idle. The scan period is every 4 msec. If there is a need to support more than 24 keys, the key matrix can be extended by adding scan column output GPIO's. The maximum key resistance is 2 kΩ, leakage between any two key matrix lines must be kept below 5 µA. The End Key is also used to power on the phone it is allocated a complete ROW of the keyboard scan. EB-X60 supports the VSCL games and keypad assignments for VSCL games refers to the below table.

■ I2C Bus Interface

A standard I2C-Bus interface is implemented, especially to control the Infineon power management device U2006 E-Power. Operation of U2006 can be controlled completely by a set of control registers. E-Gold + can write to the control register via an I2C-bus interface. Using the I2C-bus master interface on E-Gold + the system controller can control most functions of U2006 as soon as power is supplied to E-Gold +. Via the same interface E-Gold + can read status registers permitting monitoring of the state of U2001, e.g. to detect the cause of a reset or whether an external supply voltage for battery charging is applied. The controller may power-down the system or parts of it by writing to the appropriate control register. Powering down parts of the system reduces stand-by power consumption of U2006 and may additionally reduce the power-down current of the attached devices. The I2C-bus interface of E-Power is a pure slave interface. It permits fast-mode operation with clock frequencies up to 400 kHz as described in the I2C-bus specification. Spike suppression is done by analogue filtering. Error protection is used to prevent malfunction due to interference under adverse environmental conditions. For this purpose an 8-bit CRC byte is appended to each command word. Only if the CRC has been verified by U2006 the transferred command will be executed. Correct reception and execution of the transmitted command can be verified by E-Gold + by reading back the transmitted CRC byte.

■ Timer / Watchdog Timer

The MCU general purpose timer blocks contain 9 16-bit timers and 16 capture compare channels with pulse width modulation options. The Watchdog Timer provides programmable time-out periods derived from the CPU clock. If it is not served before reaching time-out, the Watchdog Timer asserts a hardware reset.

■ UART (ASC : Asynchronous/Synchronous Serial Interface)

The U2001 E-Gold + V3 has two UART ports, ASC0 and ASC1. ASC0 with automatic baudrate detection running up to 3.28 Mbaud and IrDA DS3001 support up to 115.2 kBaud. ASC1 running up to 3.25 Mbaud and with IrDA support up to 115.2 kBaud. EB-X60 uses ASC0 port for serial interface in factory and software download. ASC1 port is used for DS3001 data transmission.

■ Subscriber Identity Module (SIM)

The Chip Card Interface is a customized UART with additional features used for a 3 Volt Subscriber Identity Module (SIM) as specified by ISO 7816. It supports speed enhancement as specified in GSM 11.11 Phase 2+ with baud rates up to 100 kBaud. If the SIM card is disconnected, the chip card interface is able to power down the electrical contacts of the SIM card automatically. E-Gold + V3 features a GSM phase 11/11+ compliant SIM interface, providing support for 3 V normal and high-speed SIM cards. 1.8 V cards are supported inherently, as 1.8 V cards according to specifications, must be able to work also at 3 V. EB-X60 SIM interface is designed to support 3 V technology SIMs.

■ GSM Timer / RF Control

The GSM Timer and RF control modules are used to control all radio channel timings and to program external devices. The main goal of the GSM timer is to off-load the MCU from scheduling periodic events within a TDMA frame. It provides high flexibility in scheduling and executing events using a programmable RAM table and is able to generate timing and trigger signals as well as interrupts to both the MCU and to the DSP. The RF Control Unit transmits user defined control information to up to 5 devices via two separate serial interfaces. The RAM of the RF Control Unit holds up to 40 messages and 6 times 16 values for power amplifier ramping. The reference counter of the GSM Timer Unit is the TDMA counter of the TDMA Compare Unit. The TDMA counter is a programmable modulo 10000 D 15 bit counter, operated by a 0.461 µsec clock and allows to measure the length of one TDMA frame (4.615 msec) with a resolution of one eights of a bit. The RAM of the GSM Timer Unit contains the information at what time within a TDMA frame, one (or more) of the 26 output signals TRIG (25 : 0) change its value (called timing compare value), and the new values of all output signals at this time. One timing compare value and the corresponding TRIG (25:0) signal values are called timing event. The RAM operates like a FIFO. The TDMA Compare Unit compares the last timing compare value of the FIFO with the TDMA counter value. When both values are identical, the corresponding output values for TRIG (25 : 0) are read out of the RAM and taken over by the external signals. After a match, the RAM address is incremented by the address generator of the RAM Control Block and the next timing compare value is address decoder.

■ RTC

Real Time Clock block in U2001 E-Gold + V3 is used for EB-X60. The integrated RTC in the E-Gold + consumes only approx. 1 - 2 µA, hence backup can be provided simply by adding a large capacitance on the RTC supply. In backup mode (E-Gold + powered off) with only the RTC running, the RTC will operate down to app. 1 V. EB-X60 has very large backup capacitors. Thus, EB-X60 inserts a series resistor to avoid initial charging of the capacitor and clamps the RTC supply, preventing the RTC circuit to work during E-Gold + initialization. EB-X60 uses the micro capacitor instead of backup battery to save the cost and chip mount area. The Transceiver IC U101 (PMB6256VV1.1) set does not support the backup function in these LSIs, it is necessary to add the external regulator and power control circuit for backup battery charging. The backup battery capacity is 50 µAh (2.6 V to 0.0 V discharge).

■ Power amplifier Ramp

The PA control ensures that the power ramp up and down sequences are generated. Each power ramp up/down sequence consists of 16 values of 10-bit length which represents the shape of the rising (falling) edge of the desired ramping curve in digital form. All 10-bit values will be delivered in serial manner to the power-ramping path of GAIM.

Shape

The Ramp Shape is defined by 16 steps, the shape can be defined differently for rising and falling ramps. Typically a raised cosine shape will be used as a starting basis of the ramp shape.

■ AFC Control

The Automatic Frequency Control (AFC) Unit generates a pulse number modulated (PNM) signal which can be low pass filtered externally to make a programmable DC voltage for controlling the external VCXO. The PNM signal repeats itself with a period depending on the number of bits used in register AFCVAL. For standard applications the upper 11-bit are used and the PNM signal repeats every 2048 13 MHz clock cycles. (Approx. 158 µsec, frequency 6.35 kHz) For each 13 MHz clock input to the block, the output is driven to "1" or "0". The ratio of the number of "1"s to "0"s output in a period is proportional to the value of the AFCVAL register. The "1"s are distributed equally in a PNM period. No pulse deviates more from a perfect distribution by more than 1 input clock period. For instance if the value 7 is programmed, the leading edge of the seven 77 nsec wide pulses are separated by 293, 293, 292, 293, 292, 293 and 292 clock periods, which is near the ideal value of 292.57. The equal spacing in a period ensures that most of the energy in the signal appears at harmonics of 6.35 kHz, (in this case 7 x 6.35 kHz), and very little at 6.35 kHz. Because of this the requirements for the low pass filter are considerably reduced compared to a pulse width modulated output or a pulse number modulated signal with unequal distribution. In this example which uses 11-bits, the lowest frequency component in the spectrum of any E-Gold + V3 PNM sequence is 6.35 kHz and has an effective amplitude of less than 1 LSB.

The figure shows an AD converter path, starting from the analog inputs, the buffer amplifier, the Σ∆ modulator and digital decimating low-pass filter. The voltage is divided in an optional resistor divider to adapt to the input range of the modulators, and the resulting voltage difference to the reference voltage Vref is converted to a 6.5 Mbit/s bitstream at the output of the

Σ∆ modulator. This bitstream is converted to a 16-bit value in the decimating low pass filter.

Command register: $01C0:0000 Data register: $01C1:0000

These register are write access only.

5.2.6. IrDA

The IrDA module is mounted on the upper unit PCB. EB-X60 supports IrDA file transfer and object exchange, but does not support IrDA dial-up. In a special asynchronous mode of U2001 E-Gold+ V3, the ASC supports IrDA data transmissions up to 115.2 KBaud with fixed or programmable IrDA pulse width. An autobaud detection unit allows to detect asynchronous data frames with its baudrate andmode with automatic initialization of the baudrate generator and the mode control bits.
