Renesas Technology America Inc. is shipping its 160 MHz SH7211F single-chip microcontroller with 512 kbytes of on-chip Flash memory. The 32-bit RISC chip, the latest member of the SuperH family, uses the firm’s new SH-2A core. The CPU also employs proprietary Flash memory technology that provides virtually the same performance as when single-cycle memory accesses are performed at 160 MHz. The SH-2A core improves ROM code efficiency, so program size can be reduced by about 25 percent compared with code written for chips that have the SH-2 core. The 144-pin devices list for $19.84. The line can use peripherals designed for SH-2 cores.
