TMPR3922U

The TMPR3922U is a single-chip combined digital ASSP for PDA(peraonal digital assistants). The TMPR3922U includes of PDA system support logic, integrated with the TX3920 processor core dsigned by toshba.

Features of TMPR3922U are:(1)R3000A-based TX3920 processor core: RISC architecture developed by the MIPS grou ps, a division of silicon graphics Inc, toshiba has added its own multiply-add and branch-likely instruction; (2)built-in peripheral circuit: clock generator with built -in sixteenfold-frequency phase-locked loop, four stage write buffer; (3)low power dissipation: 3.3V(I/O)/2.5V(internal) operation.

The absolute maximum ratings and recommended operating conditions of the TMPR3922U can be summarized as:(1)supply voltage: Vss-0.5V to 4.5V; (2)input voltage: Vss-0.5 to Vddh+0.5V; (3)storage temperature:-55 to 125; (4)maximum dissipation(Ta=70): 1W. Recommended operating conditions: (1)power supply voltage: 3.0V min, 3.3V typ and 3.6V max; (2)operating temperature: 0 to 70.
