32-bit microcontroller with LCD controller and touch screen interface

Toshiba Electronics Europe has expanded its family of TFT-enabled microcontrollers with a 32-bit device that combines high-level processing, high-capacity memory, and integrated colour LCD controller in a 20mm x 20mm package. Target applications for the TMP92CF29FG will include home appliances where the trend is towards colour TFTs that enhance the user experience. Capable of operating at 80MHz, the device combines 144Kbytes of on-board RAM with a 65K colour TFT/262K colour STN LCD controller, a number of on-board peripherals, and a variety of connectivity options including a touch screen interface. Connectivity provided by the 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. On-board peripherals include a 10-bit, six-channel ADC, an 8-bit timer/counter (eight-channel), a 16-bit timer/counter (two-channel) and an RTC. An on-board SDRAM controller supports up to 512Mbits of memory, while an on-chip MAC circuit performs high-speed processing. A memory management unit supports up to 2.1Gbytes of external memory. The TMP92CF29FG is based on Toshiba’s TLCS-900/H1 32-bit CPU core, which combines RISC-level performance with the benefits of a CISC architecture. Forty-seven interrupts can be accommodated, while 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 1.4V to 1.6V and 3.0V to 3.6V respectively.

 In addition to the device, Toshiba can also supply a reference board that will allow designers to 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.
