Ultra-Low-Power 16-Bit Micro with 256Kbytes of SuperFlash™

Toshiba’s TMP91FY42FG high-performance, ultra-low-power microcontroller integrates 256Kbytes of on-board Flash and a comprehensive range of peripherals to minimise external component count and enhance programming flexibility. The micro is fully supported by a comprehensive Starter Kit, and Toshiba is offering five of these kits free-of-charge to readers of Arrow Innovation.



The TMP91FY42FG uses SuperFlash™ technology licensed from Silicon Storage Technology, Inc.

The TMP91FY42FG, Toshiba’s first 16-bit microcontroller to feature Silicon Storage Technologies’ (SST) SuperFlash memory, combines a high Flash memory capacity of 256Kbytes 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.

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

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.

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.
