Flash Programmable System Device with 8032 Microcontroller Core

STMicroelectronics 

µPSD323X

Flash Programmable System Devices

with 8032 Microcontroller Core and 64Kbit SRAM

FEATURES SUMMARY

s The µPSD323X Devices combine a Flash PSD

architecture with an 8032 microcontroller core.

The µPSD323X Devices of Flash PSDs feature

dual banks of Flash memory, SRAM, general

purpose I/O and programmable logic, supervi-

sory functions and access via USB, I2C, ADC,

DDC and PWM channels, and an on-board

8032 microcontroller core, with two UARTs,

three 16-bit Timer/Counters and two External

Interrupts. As with other Flash PSD families, the

µPSD323X Devices are also in-system pro-

grammable (ISP) via a JTAG ISP interface.

s Large 8KByte SRAM with battery back-up

option

s Dual bank Flash memories

– 128KByte or 256KByte main Flash memory

– 32KByte secondary Flash memory

s Content Security

– Block access to Flash memory

s Programmable Decode PLD for flexible address

mapping of all memories within 8032 space.

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

s USB Interface (some devices only)

s I2C interface for peripheral connections

s 5 Pulse Width Modulator (PWM) channels

s Analog-to-Digital Converter (ADC)

s Standalone Display Data Channel (DDC)

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

s 3000 gate PLD with 16 macrocells

s Supervisor functions with Watchdog Timer

s In-System Programming (ISP) via JTAG

s Zero-Power Technology

s Single Supply Voltage

– 4.5 to 5.5V

– 3.0 to 3.6V
