PR31700ABC

The PR31700ABC is a kind of a single-chip digital ASSP (Application Specific Stand Product). The device includes system support logic, integrated with the PR3901 Processor Core designed by Philips Semiconductors. The typical applications include HPCs (Handheld Personal Computers), Palm-size PCs, Screenphones, Smartphones, and other vertical market applications in the mobile computing and communication markets.

There are some features about PR31700ABC as follows: (1) built-in peripheral circuit: clock generator with built-in eightfold-frequency phase-locked loop (PLL), four-stage write buffer, a high performance and flexible bus interface unit, multiple DMA channels, memory controller for DRAM, HDRAM, SDRAM, SRAM, ROM, Flash Memory and PCMCIA, power management unit and big/little endian; (2) low power dissipation: 3.3 V operation, standby current 10 A (typ), CPU clock stop mode, power down modes for individual internal peripheral modules; (3) plastic LQFP 208-pin package.

What comes next is about the PR31700ABC absolute maximum ratings. (1): VDD (power supply voltage) is from VSS-0.5 to 4.5 V; (2): VIN (input voltage) is from VSS-0.5 to VDD+0.5 V; (3): storage temperature (Tstg) is from -55 to 125; (4): Pd (maximum dissipation (Tamb=70)) is 1 W.
