APPLICATION NOTE

Conversion Guide, uPSD3200 to uPSD3300 Series

Overview

The uPSD family currently consists of two series, uPSD3200 and uPSD3300. Both are available in the same kind of packages, but there are a few differences in pin definitions. This document describes the differences and suggests methods to easily migrate designs from the uPSD3200 series to uPSD3300. You can implement simple techniques on your printed circuit board to accept either a uPSD3200 or a uPSD3300 during manufacturing.

Pin differences will be presented two categories:

1.Mandatory pin function changes for all applications

2.Conditional pin function changes depending on the application.

There are also differences in SFRs and interrupt vectors, which may impact firmware depending on the application. These differences are identified to help you migrate your firmware.

For simplicity, the uPSD3200 series will be referred in this document as 3200, and the Turbo uPSD3300 series will be referred to as 3300.

1 Summary of Differences

1Summary of Differences

MCU CORE VOLTAGE: The 3300 MCU core requires a 3.3V supply, even when used in a 5V system. This means two separate supplies (5V VDD and 3.3V VCC) are required in a 5V system, but just one supply (3.3V VCC) is required for a 3.3V system. In contrast, 3200 devices use only a single VCC supply, which is 5V VCC for 5V devices, or 3.3V VCC for 3.3V devices.

MCU CORE: The 3200 MCU requires 12 clocks per instruction but the 3300 uses just 4 clocks. The 3300 does not have an optional 12-clock operation mode. NO modifications are needed to 3200 firmware for standard 8032 functions unless timing was established with software loops. Modifications ARE required for firmware controlling some peripherals when migrating to 3300.

PWM: The five 8-bit PWM channels of the 3200 are implemented with the Programmable Counter Array (PCA) in the 3300, which has six 16-bit timer/counter modules. There are new SFRs, and some PWM pin number assignments have changed on the 3300.

ADC: The four 8-bit ADC channels of the 3200 are implemented using four of the eight 10bit ADC channels on the 3300. There are new SFRs, but there are no ADC input pin number changes. The ADC reference voltage (VREF) input pin is not available on 52-pin 3300 devices and VREF is shared internally with the 3.3V VCC core supply. 80-pin 3300 devices do have an ADC VREF pin, and its max input voltage is VCC (3.3V). The max input voltage on any 3300 ADC input is VCC (3.3V) even in a 5V system.

LVD: Both 5V and 3.3V 3300 devices have Low-Voltage Detect (LVD) trip point set for the 3.3V VCC supply level (2.5V). This must be considered when designing 5V system.

WATCHDOG: The watchdog timer is enabled after reset on 3200 devices, but it is disabled after reset on 3300 devices.

I/O Characteristics: The 3.3V 3300 devices have 5V tolerant I/O on ports 1, 3, and 4, but ports A,B,C, and D are not 5V tolerant. The 3.3V 3200 devices do not have any 5V tolerant I/O.

UART and I2C: Minor changes to SFR definitions.

USB and DDC: No USB or DDC interfaces are on the 3300.

2 Summary of new uPSD3300 functions

Listed below are new functions on the 3300 that were not available on the 3200. Obviously there is no direct migration path for these new functions since the 3200 does not have them. However, you should be aware of the new functions so you can plan to take advantage of them.

SPI: An SPI bus master interface is provided on the 3300.

ADC: Eight 10-bit ADC inputs are provided, compared to only four 8-bit ADC inputs on the 3200.

IrDA: The 2nd UART channel supports IrDA protocol, which be connected directly to an IR transceiver.

PCA: The Programmable Counter Array unit has six 16-bit timer/counter (TC) modules that can be used for PWM, Capture/Compare, Timers, or Counters. Three of the six TC modules can operate from one time base, and the other three TC modules can operate from another time base if desired. These six TC modules are in addition to the standard three 16-bit timer units inside the 8032 MCU core, bringing a total of nine 16-bit timer/ counters. The 3200 provides only the three standard 16-bit 8032 timers.

MCU Core: The 3300 Turbo MCU core has a six-deep instruction prefetch queue and a four-way branching address cache to increase performance. Code in smaller localities operate very fast. No special firmware is required to take advantage of the prefetch queue or branching cache, other than writing to an SFR to enable these features. Be aware that firmware timing loops will not be accurate because of the non-deterministic nature of pipeline and cache architecture. Please use one of the many hardware timer modules to create timing functions, not firmware loops.

MCU Core: The 3300 Turbo MCU core includes dual data pointers to speed data transfers of XDATA. The pointers can auto-increment and auto-decrement, providing rapid data movement from source to destination locations. The 3200 has one only data pointer.

JTAG Debug: The JTAG port now functions as a debug port in addition to In-System Programming (ISP). This eliminates the need for conventional hardware In-Circuit Emulation (ICE) tools.

Debug: The 3300 has a dedicated debug input/output pin. As an output, it can signal that a specified debug event has occurred, as an input it can trigger a debug event to begin (breakpoint, trace, and so forth).

MCU Clock: 3.3V 3300 devices can be clocked up to 40MHz, unlike 3.3V 3200 with 24MHz max.

MCU Clock: 8032 MCU clock can be divided internally for lower power operation. The MCU may change the clock divider ratio on-the-fly using SFRs. This affects the MCU only, not peripheral clocks.

Cross-Bar I/O: Peripheral functions on Port 1 are also available on Port 4 (cross-bar switch), providing more flexibility. There is no need to sacrifice one peripheral function when two functions are available on a single pin, just use the other port.

High Current I/O: Eight I/O pins on Port 4 are each capable of sinking or sourcing 10mA, for both 3.3V and 5.0V 3300. In contrast, 3.3V 3200 pins are capable of sinking 4mA each, 5V 3200 sink 8mA each.

5V Tolerant I/O: The following pins are 5V tolerant on 3.3V, 52-pin 3300 devices: P1.1 through P1.7, P3.1 through P3.7, P4.1 through P4.7, and RESET_IN_. On 3.3V, 80-pin 3300 devices, the following pins are also 5V tolerant: MCU_AD0 through MCU_AD7,

MCU_A8 through MCU_A11, RD_, WR_, and _PSEN. In contrast, 3.3V 3200 devices had no 5V tolerant I/O pins.

Note: Note: The PSD functions have NOT changed at all from 3200 to 3300. These functions include PLD, memory mapping, memory management (code space vs. data space, and paging), Flash memories, SRAM memory, PSD I/O. All changes in the 3300 are related to the MCU and not the PSD.

Note: 1 For 5V applications, VDD must be connected to 5.0V source. For 3.3V applications, VDD must be connected to 3.3V source.

2These signals can be used on one of two different ports (Port 1 or Port 4) for flexibility. Default is Port 1.

3VREF and 3.3V VCC are shared. ADC channels must use 3.3V as VREF for 52-pin package.
