Flash Programmable System Devices  
with 8032 Microcontroller Core  
FEATURES SUMMARY  
The uPSD325X devices combine a Flash PSD  
Figure 1. 52-lead, Thin, Quad, Flat Package  
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, supervi-  
2
sory functions and access via USB, I C, 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 pro-  
grammable (ISP) via a JTAG ISP interface.  
TQFP52 (T)  
Large 32KByte SRAM with battery back-up  
option  
Dual bank Flash memories  
– 128KByte or 256KByte main Flash memory  
– 32KByte secondary Flash memory  
Content Security  
Figure 2. 80-lead, Thin, Quad, Flat Package  
– Block access to Flash memory  
Programmable Decode PLD for flexible address  
mapping of all memories within 8032 space.  
High-speed clock standard 8032 core (12-cycle)  
USB Interface (some devices only)  
2
I C interface for peripheral connections  
5 Pulse Width Modulator (PWM) channels  
Analog-to-Digital Converter (ADC)  
Standalone Display Data Channel (DDC)  
Six I/O ports with up to 46 I/O pins  
3000 gate PLD with 16 macrocells  
Supervisor functions with Watchdog Timer  
In-System Programming (ISP) via JTAG  
Zero-Power Technology  
TQFP80 (U)  
Single Supply Voltage  
– 4.5 to 5.5V  
– 3.0 to 3.6V
