μPSD3251F
8032 MCU with Programmable Logic
FEATURES SUMMARY
I
The μPSD3251F device combines a Flash PSD
architecture with an 8032 microcontroller core.
The μPSD3251F device of Flash PSDs feature
dual banks of Flash memory, SRAM, general
purpose I/O and programmable logic, supervi-
sory functions and access via I
2
C, ADC, 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 μPSD3251F device are also in-sys-
tem programmable (ISP) via a JTAG ISP inter-
face.
