UPSD3253B

UPSD3254A, UPSD3254BV UPSD3253B, UPSD3253BV 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...
