Flash Programmable System Devices

with 8032 Microcontroller Core

FEATURES SUMMARY

■ The uPSD325X devices combine a Flash PSD

Figure 1. 52-lead, Thin, Quad, Flat Package

architecture with an 8032 microcontroller core.

The uPSD325X 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, I C, 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

uPSD325X devices are also in-system pro-

grammable (ISP) via a JTAG ISP interface.

TQFP52 (T)

■ Large 32KByte SRAM with battery back-up

option

■ Dual bank Flash memories

– 128KByte or 256KByte main Flash memory

– 32KByte secondary Flash memory

■ Content Security

Figure 2. 80-lead, Thin, Quad, Flat Package

– Block access to Flash memory

■ Programmable Decode PLD for flexible address

mapping of all memories within 8032 space.

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

■ USB Interface (some devices only)

■ I C interface for peripheral connections

■ 5 Pulse Width Modulator (PWM) channels

■ Analog-to-Digital Converter (ADC)

■ Standalone Display Data Channel (DDC)

■ Six I/O ports with up to 46 I/O pins

■ 3000 gate PLD with 16 macrocells

■ Supervisor functions with Watchdog Timer

■ In-System Programming (ISP) via JTAG

■ Zero-Power Technology

TQFP80 (U)

■ Single Supply Voltage

– 4.5 to 5.5V

– 3.0 to 3.6V
