FEATURES SUMMARY

■ The μPSD3200 Family combines a Flash PSD

architecture with an 8032 microcontroller core

The μPSD3200 Family of Flash PSDs features

dual banks of Flash memory, SRAM, general

purpose I/O and programmable logic, supervisory

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 one External

Interrupt. As with other Flash PSD families, the

μPSD3200 Family is also in-system programmable (ISP) via a JTAG ISP interface.

■ Large 8 KByte SRAM with battery back-up

option

■ Programmable Decode PLD for flexible address

mapping of all memories.

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

■ USB Interface (μPSD3234A-40U6 only)

■ I2C interface for peripheral connections

■ Five Pulse Width Modulator (PWM) channels

■ Standalone Display Data Channel (DDC)

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

■ 3000 gate PLD with 16 macrocells

■ Supervisor functions

■ In-System Programming (ISP) via JTAG

■ Zero-Power Technology

■ Single Supply Voltage

– 4.5 to 5.5 V

– 3.0 to 3.6 V
