Toshiba America Electronic Components Inc. (TAEC) has announced the availability of a new 32bit, single-chip MIPS-based reduced instruction set computer microcontroller (MCU) with 2Mbyte of on-chip NANO FLASH memory. Labeled TMP19A64F20AXBG and operating at 54MHz, this MCU is designed for battery-operated digital consumer applications, including digital video cameras.

Roland Gehmann, business development manager for TAEC's ASSP business unit, claimed that the TMP19A64F20AXBG, with its 2Mbyte of NANO FLASH memory, has the largest memory capacity currently available in the industry. "This high-density embedded memory is a significant technical milestone that enables the control of large programs with a single chip," Gehmann added.

TAEC said the TMP19A64F20AXBG integrates the Toshiba TX19A core, 2Mbyte of NANO FLASH memory and 64Kbytes of RAM. It has a backup mode function that reduces power consumption to 5?A at 2.7V, by suppressing current leakage even when in standby mode. This function also supports the real-time clock and a small amount of RAM.

Other built-in functions include a 24-channel by 10bit high-speed analog-to-digital converter (ADC) with a conversion speed of 8.44?s and an 8-channel high-speed serial interface. The device features a MAC capability of 32bit by 32bit plus 64bit in a single clock cycle.

NANO FLASH is a new technology for embedded flash MCUs that combines the attributes of a NAND flash cell and a NOR peripheral circuit to create high-density embedded memory with low power consumption.

Samples of the TMP19A64F20AXBG NANO FLASH MCU are already available and the device is in volume production. Pricing of the TMP19A64F20AXBG is $27 in 10,000-piece quantities.

A mask ROM version, TMP19A64C1DXBG, is also available with sample shipments planned to start this month. Pricing of TMP19A64C1DXBG is expected to be $18 in 10,000-piece quantities. Mass production is expected to begin June 2006. The combined production volume of the NANO FLASH and mask ROM versions is expected to total 500,000 pieces per month.
