Flash Programmable System Devices with 8032 Microcontroller Core
FEATURES SUMMARY s The uPSD325X devices combine a Flash PSD
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, 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 two External Interrupts.
As with other Flash PSD families, the uPSD325X devices are also in-system programmable (ISP) via a JTAG ISP interface.
s Large 32KByte SRAM with battery back-up option
s Dual bank Flash memories
– 128KByte or 256KByte main Flash memory
– 32KByte secondary Flash memory
s Content Security
– Block access to Flash memory
s Programmable Decode PLD for flexible address mapping of all memories within 8032 space.
s High-speed clock standard 8032 core (12-cycle)
s USB I...
