Processor takes novel Flash memory onboard

A high-performance 32bit RISC microprocessor integrates Toshiba's novel Nano Flash ultra-low-power embedded memory and a large number of peripherals into a compact 193-pin package.

Toshiba Electronics Europe has developed a high-performance 32bit RISC microprocessor that integrates the company's newly developed Nano Flash ultra-low-power embedded Flash memory and a large number of peripherals into a compact 193-pin package.

The TMP19A43 is the first device to feature Toshiba's Nano Flash technology and provides a single-chip solution for large-scale systems.

Potential applications include high-end portable electronic equipment and other designs that require high performance, low power consumption and minimum component counts.

Developed specifically for use as embedded microprocessor memory, Nano Flash brings together the benefits of NOR Flash and NAND Flash in a single technology.

The result is embedded memory that allows both high-speed random access and high-speed programming, while maintaining very low levels of power consumption.

Toshiba's TMP19A43 32bit RISC processor features 512Kbyte of Nano Flash as well as 24Kbyte of built-in RAM.

The device is based on the established TX19A CPU core that enables high code efficiency and superior interrupt response and operates with clock speeds up to 40MHz.

Internal supply voltages are between 1.35 to 1.65V, and I/O voltages are from 2.7 to 3.6V.

The new processor incorporates a variety of peripherals including a 17-channel 16/32bit timer, a DMA controller, a 16-channel 10bit ADC that allows high-speed conversion (1.155s), two channels of 8bit DAC, a watchdog timer and a clock timer.

Sixteen external interrupt pins and 32-key-on wakeup pins are available for key inputs such as standby release input functions.

Six high-speed serial interface channels provide designers with the flexibility to meet the demands of high-end designs.

The TMP19A43 is supplied in a 193-pin FBGA package measuring just 12 x 12 x 1.4mm.

In addition to the Nano Flash device, Toshiba will also offer a version with on-chip MASK ROM.
