µPSD325X

Flash Programmable System Devices

with 8032 Microcontroller Core and 256Kbit SRAM

FEATURES SUMMARY

s

The µPSD325X devices combine a Flash PSD

architecture with an 8032 microcontroller core.

The µPSD325X 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

µPSD325X devices are also in-system pro-

grammable (ISP) via a JTAG ISP interface.
