UPSD3212C
UPSD3212CV
Flash Programmable System Devices
with 8032 Microcontroller Core and 16Kbit SRAM
FEATURES SUMMARY
s The uPSD321X Devices combine a Flash PSD
architecture with an 8032 microcontroller core.
The uPSD321X Devices of Flash PSDs feature
dual banks of Flash memory, SRAM, general
purpose I/O and programmable logic, supervi-
sory functions and access via I2C, ADC and
PWM channels, and an on-board 8032 micro-
controller core, with two UARTs, three 16-bit
Timer/Counters and two External Interrupts. As
with other Flash PSD families, the uPSD321X
Devices are also in-system programmable (ISP)
via a JTAG ISP interface.
s Large 2KByte SRAM with battery back-up
option
s Dual bank Flash memories
– 64KByte main Flash memory
– 16KByte 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 I2C interface for peripheral connections
s 5 Pulse Width Modulator (PWM) channels
s Analog-to-Digital Converter (ADC)
s Six I/O ports with up to 46 I/O pins
s 3000 gate PLD with 16 macrocells
s Supervisor functions with Watchdog Timer
s In-System Programming (ISP) via JTAG
s Zero-Power Technology
s Single Supply Voltage
– 4.5 to 5.5V
– 3.0 to 3.6V
