100-pin 8bit MCU eliminates need for external LCD drivers

Toshiba has expanded its family of high-performance CMOS 8bit microcontrollers (MCUs) with a device that integrates 32KB of flash memory, an LCD driver circuit, and key peripherals and interfaces into a compact 100-pin package.

Supplied in a compact P-QFP100 package, the TMP86FM25 flash memory MCU will suit applications ranging from home appliances to EPOS systems and industrial control equipment. On-board flash memory allows designers to use the same device to offer different levels of functionality simply by changing program software, while the integrated peripherals minimize the need for external components. In addition to the 60seg x 16com LCD driver and booster circuit and the onboard flash memory, the TMP86FM25 integrates 2KB of boot ROM, 2KB of RAM and an 8bit, 8-channel ADC. A single-channel 18bit timer, a four-channel 8bit timer, and a watchdog timer are also available. Serial interfaces take the form of a 2-channel, 8bit SIO and a single-channel UART, while 42 pins are available for general I/O.

Dual frequency, voltage operation
Toshiba's new IC is based on the company's TLCS-870/C CPU core. This core offers 731 basic operations and enables operation at up to 16MHz with voltages of between 2.7V and 3.6V. With an operating speed of 8MHz, the TMP86FM25 can be used with voltages down to 1.8V. In addition to normal operation, three IDLE modes, a SLOW mode, two SLEEP modes and a STOP mode ensure minimum power consumption across a range of operating conditions.

Starter kit

Designers can speed the development of embedded applications based on the new microcontroller-family with a Toshiba Microcontroller Starter Kit. The kit provides all of the tools required for rapid development and debugging, and includes a flash memory programmer and extensive software libraries.
