Toshiba Electronics Europe has developed its first 16bit microcontroller to feature Silicon Storage Technologies’ (SST) Superflash memory. The TMP91FY42FG combines a high Flash memory capacity of 256Kbyte with a variety of I/O functions and onboard 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.

The TMP91FY42FG high-speed 16bit microcontroller is based on Toshiba’s ultra-low-power TLCS-900/L1 processor core and will operate with voltages of between 2.7 and 3.6V.

Minimum instruction execution time is just 148ns at 27MHz.

Three standby modes including a programmable IDLE option further reduce overall power consumption.

Toshiba’s 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.

ISP mode allows upgrades and fixes in the field under control of the user program, removing the need to switch off the output to an LCD panel or active output controls.

Designed for medium- to high-end applications, the new TMP91FY42FG microcontroller features an integrated 10bit, eight-channel analogue-to-digital convertor (ADC), an eight-channel 8bit timer, a two-channel 16bit timer, and a watchdog timer.

I/O functionality includes a two-channel SIO/UART, an I2C interface, support for IrDA version 1.0 (115.2Kbit/s) and 81 I/O ports.

The ultra-low-power TLCS-900/L1 core combines a general-purpose register bank for rapid context switching with a high-speed, four-channel micro-DMA and powerful bit manipulation and arithmetic instructions.

The TMP91FY42FG offers full compatibility with other Toshiba devices based on the TLCS-900/L and TLCS-900/H cores.

In addition to the high-capacity SuperFlash, the new microcontroller’s onboard memory also includes 16Kbyte of internal RAM and 4Kbyte of mask ROM for booting.

External memory expansion to 16Mbyte is fully supported.

The TMP91FY42FG is supplied in a compact 100-pin LQFP package with dimensions of 14 x 14mm.
