Product Summary
The TMPR3904AFG is a single-chip, integrated digital ASSP for the Personal Digital Assistants (PDA). Figure 1.1.1 shows a block diagram of the overall PDA system. The TMPR3904AFG consists of the PDA system support logic, integrated with an embedded TX39/H Processor core designed by TOSHIBA. The TMPR3904AFG consists of a TX39/H Processor core with 4 Kbytes of instruction cache memory and 1 Kbyte of data cache memory, plus integrated functions for interfacing to numerous system components and external I/O modules. The TX39/H Processor core is also augmented with a single-cycle multiply/accumulate module to allow integrated DSP functions, such as a software modem for highperformance standard data and fax protocols.
Parametrics
TMPR3904AFG absolute maximum ratings: (1)Supply voltage (I/O)VDD VSS: -0.5 to 4.5 V; (2)Supply voltage (Internal Logic)VDDL VSS: -0.5 to VDDH V; (3)Input voltage VIN VSS: -0.5 to VDDH + 0.5 V; (4)Storage temperature TSTG: -55 to 125 ℃; (5)Maximum dissipation (Ta = 70℃)PD: 1 W.
Features
TMPR3904AFG features: (1)32-bit TX39/H Processor core, cache memory, multiply-accumulate module, multi-channel DMA controller, bus interface unit and memory controller, power management, and other peripheral subsystems all on a single integrated chip; (2)minimal number of inter-chip connections; (3)Maximum operation frequency: 58 MHz (TMPR3911BU and TMPR3911BXB)92 MHz (TMPR3912AU-92 and XB-92); (4)entire TMPR3911/12 operation is 3.3 V (in case of TMPR3911BU/BXB, I/O: 3.3 V, internal: 2.6 V); (5)real-time clock based on 32.768 kHz reference; (6)Processor core clock stop state for low standby current; (7)power-down modes for individual internal peripheral modules.
