GENERAL DESCRIPTION

The MX27C1024 is a 5V only, 1M-bit, One Time Programmable Read Only Memory. It is organized as 64K words by 16 bits per word(MX27C1024), 128K x 8 or 64K x 16(MX27C1100), operates from a single + 5 volt supply, has a static standby mode, and features fast single address location programming. All programming signals are TTL levels, requiring a single pulse. For programming outside from the system, existing

Operating current: 40mA

Standby current: 100uA

Package type:

-40 pin plastic DIP

-40 pin plastic SOP

-44 pin PLCC

-40pin 10 x 14mm TSOP(I)

EPROM programmers may be used. The MX27C1100/ 1024 supports a intelligent fast programming algorithm which can result in programming time of less than thirty seconds.

This EPROM is packaged in industry standard 40 pin dual-in-line packages, 40 lead SOP, 44 lead PLCC, and 40 lead TSOP(I) packages.

MX27C1100/27C1024

FUNCTIONAL DESCRIPTION

THE PROGRAMMING OF THE MX27C1100/1024

When the MX27C1100/1024 is delivered, or it is erased, the chip has all 1M bits in the "ONE" or HIGH state. "ZEROs" are loaded into the MX27C1100/1024 through the procedure of programming.

For programming, the data to be programmed is applied with 16 bits in parallel to the data pins.

VCC must be applied simultaneously or before VPP, and removed simultaneously or after VPP. When programming an MXIC EPROM, a 0.1uF capacitor is required across VPP and ground to suppress spurious voltage transients which may damage the device.

FAST PROGRAMMING

The device is set up in the fast programming mode when the programming voltage VPP = 12.75V is applied, with VCC = 6.25 V and PGM = VIL(or OE = VIH) (Algorithm is shown in Figure 1). The programming is achieved by applying a single TTL low level 100us pulse to the PGM input after addresses and data line are stable. If the data is not verified, an additional pulse is applied for a maximum of 25 pulses. This process is repeated while sequencing through each address of the device. When the programming mode is completed, the data in all address is verified at VCC = VPP = 5V ± 10%.

PROGRAM INHIBIT MODE

Programming of multiple MX27C1100/1024's in parallel with different data is also easily accomplished by using the Program Inhibit Mode. Except for CE and OE, all like inputs of the parallel MX27C1100/1024 may be common. A TTL low-level program pulse applied to an MX27C1100/1024 CE input with VPP = 12.5 ± 0.5 V will program the MX27C1100/1024. A high-level CE input inhibits the other MX27C1100/1024s from being programmed.

PROGRAM VERIFY MODE

Verification should be performed on the programmed bits to determine that they were correctly programmed. The verification should be performed with OE and CE at

VIL(for MX27C1024), OE at VIL, CE at VIH(for MX27C1100)and VPP at its programming voltage.

AUTO IDENTIFY MODE

The auto identify mode allows the reading out of a binary code from an EPROM that will identify its manufacturer and device type. This mode is intended for use by programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. This mode is functional in the 25°C ± 5°C ambient temperature range that is required when programming the MX27C1100/1024.

To activate this mode, the programming equipment must force 12.0 ±0.5 V on address line A9 of the device. Two identifier bytes may then be sequenced from the device outputs by toggling address line A0 from VIL to VIH. All other address lines must be held at VIL during auto identify mode.

Byte 0 ( A0 = VIL) represents the manufacturer code, and byte 1 (A0 = VIH), the device identifier code. For the MX27C1100/1024, these two identifier bytes are given in the Mode Select Table. All identifiers for manufacturer and device codes will possess odd parity, with the MSB (Q15) defined as the parity bit.

READ MODE

The MX27C1100/1024 has two control functions, both of which must be logically satisfied in order to obtain data at the outputs. Chip Enable (CE) is the power control and should be used for device selection. Output Enable (OE) is the output control and should be used to gate data to the output pins, independent of device selection. Assuming that addresses are stable, address access time (tACC) is equal to the delay from CE to output (tCE). Data is available at the outputs tOE after the falling edge of OE's, assuming that CE has been LOW and addresses have been stable for at least tACC - t OE.

WORD-WIDE MODE

With BYTE/VPP at VCC ± 0.2V outputs Q0-7 present data Q0-7 and outputs Q8-15 present data Q8-15, after CE and OE are appropriately enabled.

MX27C1100/27C1024

BYTE-WIDE MODE

With BYTE/VPP at GND ± 0.2V, outputs Q8-15 are tristated. If Q15/A-1 = VIH, outputs Q0-7 present data bits Q8-15. If Q15/A-1 = VIL, outputs Q0-7 present data bits Q0-7.

STANDBY MODE

The MX27C1100/1024 has a CMOS standby mode which reduces the maximum VCC current to 100 uA. It is placed in CMOS standby when CE is at VCC ± 0.3 V. The MX27C1100/1024 also has a TTL-standby mode which reduces the maximum VCC current to 1.5 mA. It is placed in TTL-standby when CE is at VIH. When in standby mode, the outputs are in a high-impedance state, independent of the OE input.

TWO-LINE OUTPUT CONTROL FUNCTION

To accommodate multiple memory connections, a twoline control function is provided to allow for:

1.Low memory power dissipation,

2.Assurance that output bus contention will not occur.

It is recommended that CE be decoded and used as the primary device-selecting function, while OE be made a common connection to all devices in the array and connected to the READ line from the system control bus. This assures that all deselected memory devices are in their low-power standby mode and that the output pins are only active when data is desired from a particular memory device.

SYSTEM CONSIDERATIONS

During the switch between active and standby conditions, transient current peaks are produced on the rising and falling edges of Chip Enable. The magnitude of these transient current peaks is dependent on the output capacitance loading of the device. At a minimum, a 0.1 uF ceramic capacitor (high frequency, low inherent inductance) should be used on each device between Vcc and GND to minimize transient effects. In addition, to overcome the voltage drop caused by the inductive effects of the printed circuit board traces on EPROM

arrays, a 4.7 uF bulk electrolytic capacitor should be used between VCC and GND for each eight devices. The location of the capacitor should be close to where the power supply is connected to the array.
