Epson's new chipset for mobile terminals is based on Hitachi SH3 processor, the E0C37109.
The E0C37109 is an application-specific standard prod- uct (ASSP) that contains Hitachi 32 bit RISC SH7709-compatible chip as the CPU. In addition to the existing peripheral functions of the SH7709, the chip has a built-in LCD controller compatible with Epson SED1354 and incorporates various interface functions as companion functions such as PCMCIA, compact flash, keyboard and mouse and ISA bus subset. The company says that the peripheral functions make it possible to configure an application system for portable information equipment using LCD or POS and other terminal equipment by adding only a few external circuits (eg memory and buffer). Furthermore, the low-power design of these devices helps to maximise the battery life of portable and mobile equipment. With all the functions necessary for embedded systems in portable information equipment, multimedia equipment, etc integrated on a single chip, the E0C37109 is a 32 bit, single-chip RISC microcomputer that can offer a good cost-performance ratio.
An upgraded version of this chip, the E0C37109W is guaranteed to run under Windows CE.
The power supply is 3,3 V (±0,3 V) and allows a 5 V interface for PCMCIA. The maximum operating frequency is 80 MHz for the CPU and 40 MHz for internal peripherals and external bus access. The chip is offered in a T-BGA 420 pin package with 35 x 35 mm2, 1,7 mm depth and a 1,27 mm pitch.
The E0C37109 can be combined with Epson's E0C37120, a multifunction buffer IC suitable for use as a PCMCIA interface buffer and 3,3-5 V conversion level shifter.
The E0C37120 is designed to be particularly effective when it is used with the E0C37109 (MPU) 32 bit single-chip RISC microcomputer, claims Epson. When used in this way, it provides superior characteristics as an interface buffer for PCMCIA cards capable of hot insertion/removal.
