SUMMARY DESCRIPTION

■ Dual bank Flash memories

– Concurrent operation, read from memory while erasing and writing the other. In-Application Programming (IAP) for remote updates

– Large 128KByte or 256KByte main Flash memory for application code, operating sys tems, or bit maps for graphic user interfaces

– Large 32KByte secondary Flash memory di vided in small sectors. Eliminate external EE PROM with software EEPROM emulation

– Secondary Flash memory is large enough for sophisticated communication protocol (USB) during IAP while continuing critical system tasks

■ Large SRAM with battery back-up option

– 32KByte SRAM for RTOS, high-level languages, communication buffers, and stacks

■ Programmable Decode PLD for flexible address mapping of all memories

– Place individual Flash and SRAM sectors on any address boundary

– Built-in page register breaks restrictive 8032 limit of 64KByte address space

– Special register swaps Flash memory segments between 8032 “program” space and “data” space for efficient In-Application Programming

■ High-speed clock standard 8032 core (12-cycle)

– 40MHz operation at 5V, 24MHz at 3.3V

– 2 UARTs with independent baud rate, three 16-bit Timer/Counters and two External Interrupts

■ USB Interface (some devices only)

– Supports USB 1.1 Slow Mode (1.5Mbit/s)

– Control endpoint 0 and interrupt endpoints 1 and 2

■ I2C interface for peripheral connections

– Capable of master or slave operation

■ 5 Pulse Width Modulator (PWM) channels

– Four 8-bit PWM units

– One 8-bit PWM unit with programmable period

■ 4-channel, 8-bit Analog-to-Digital Converter (ADC) with analog supply voltage (VREF)

■ Standalone Display Data Channel (DDC)

– For use in monitor, projector, and TV applications

– Compliant with VESA standards DDC1 and DDC2B

– Eliminate external DDC PROM

■ Six I/O ports with up to 50 I/O pins

– Multifunction I/O: GPIO, DDC, I2C, PWM, PLD I/O, supervisor, and JTAG

– Eliminates need for external latches and logic

■ 3000 gate PLD with 16 macrocells

– Create glue logic, state machines, delays, etc.

– Eliminate external PALs, PLDs, and 74HCxx

– Simple PSDsoft Express software ...Free

■ Supervisor functions

– Generates reset upon low voltage or watch dog time-out. Eliminate external supervisor device

– RESET Input pin; Reset output via PLD

■ In-System Programming (ISP) via JTAG

– Program entire chip in 10 - 25 seconds with no involvement of 8032

– Allows efficient manufacturing, easy product testing, and Just-In-Time inventory

– Eliminate sockets and pre-programmed parts

– Program with FlashLINKTM cable and any PC

■ Content Security

– Programmable Security Bit blocks access of device programmers and readers

■ Zero-Power Technology

– Memories and PLD automatically reach standby current between input changes

■ Packages

– 52-pin TQFP

– 80-pin TQFP: allows access to 8032 address/data/control signals for connecting to external peripherals
