µPSD323X Flash Programmable System Devices with 8032 Microcontroller Core and 64Kbit SRAM FEATURES SUMMARY s The µPSD323X Devices combine a Flash PSD architecture with an 8032 microcontroller core. The µPSD323X 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 µPSD323X Devices are also in-system programmable (ISP) via a JTAG ISP interface. s Large 8KByte 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 Interface (some d...
