Microcontroller drives colour displays

Low-power 32bit MCU combines high-level processing, high-capacity memory and a colour LCD controller in a compact 20 x 20mm package.

Toshiba Electronics Europe (TEE) has expanded its family of TFT-enabled microcontrollers with a high-performance low-power-consumption 32bit device that combines high-level processing, high-capacity memory and integrated colour LCD controller in a compact 20 x 20mm package.

Target applications for the TMP92CF29FG will include new and emerging home appliances where the trend is towards colour TFTs that enhance the user experience.

Capable of operating at 80MHz, the new TMP92CF29FG combines 144Kbyte of onboard RAM with a 64K colour TFT/256K colour STN LCD controller, a number of onboard peripherals, and a variety of connectivity options including a touch screen interface.

In addition to the integration, use of an LQFP package - rather than the BGA package typical of devices with this level of functionality - allows further cost reduction through use of simpler PCB designs.

Connectivity provided by the new microcontroller includes a two-channel MLC/SLC NAND Flash interface, an SD card interface and single-channel I2S, I2C bus and SIO/UART functionality.

A single-channel full-speed USB controller is also provided.

Onboard peripherals include a 10bit six-channel ADC, an 8bit timer/counter (eight-channel), a 16bit timer/counter (two-channel) and an RTC.

An onboard SDRAM controller supports up to 512Mbit of memory, and an on-chip MAC circuit performs high-speed processing.

A memory management unit supports up to 2.1Gbyte of external memory.

The TMP92CF29FG is based on Toshiba's TLCS-900/H1 32bit CPU core, which combines RISC-level performance with the benefits of a CISC architecture.

Up to 47 interrupts can be accommodated, and three HALT modes and a "key on wakeup" facility minimise power consumption during standby mode.

Supplied in a compact, 176-pin LQFP, the TMP92CF29FG operates with internal and I/O voltages of 1.4-1.6 and 3.0-3.6V, respectively.

In addition to the device, Toshiba can also supply a reference board that will allow designers to quickly develop applications based on the TMP92CF29FG.

This board combines the microcontroller with all necessary interfaces and peripherals, including TFT displays in a range of size options.

The board is supplied with a comprehensive suite of software that further simplifies the implementation of advanced user interface designs.
