Ultra-low power 16-bit micro has new high-capacity SuperFlash memory

22 March 2006 DSP, Micros & Memory

The TMP91FY42FG, Toshiba's first 16-bit microcontroller to feature Silicon Storage Technologies' (SST) SuperFlash memory, combines a high flash memory capacity of 256 KB with a variety of I/O functions and on-board peripherals. The result is a highly integrated, ultra-low-power device that minimises external component count and gives designers an enhanced level of programming flexibility. It operates with voltages of between 2,7 V and 3,6 V. Minimum instruction execution time is just 148 ns at 27 MHz. Toshiba says that its SuperFlash implementation can be programmed much faster than many alternative flash technologies, while the availability of three distinct programming modes - 'parallel', 'serial PROM', and 'in system programming (ISP)' - provides for both pre- and post-production programming flexibility. Designed for medium- to high-end applications, this microcontroller features an integrated 10-bit, 8-channel ADC, an 8-channel 8-bit timer, a 2-channel 16-bit timer, and a watchdog timer. I/O functionality includes a 2-channel SIO/UART, an I²C interface, support for IrDA and 81 I/O ports. The TMP91FY42FG microcontroller also includes 16 KB internal RAM and 4 KB of mask ROM for booting. It is supplied in 100-pin LQFP 14 x 14 mm package.
