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.
