Toshiba Rolls Out 16-Bit and 32-Bit Embedded Flash Microcontrollers

Toshiba America Electronic Components, Inc. (TAEC) today announced the broadening of its embedded flash microcontroller (MCU) product line with the addition of two new 16-bit MCUs and a new 32-bit MCU based on SuperFlash(R) technology. TMP91FW40FG is Toshiba’s first 16-bit SuperFlash-based MCU to incorporate an LCD controller and was designed for electronic metering and similar applications that require 16-bit performance to drive an LCD display. TMP91FW60FG/DFG is a 16-bit device that offers a combination of 128 Kbytes of flash memory and 8 Kbytes of RAM plus 5 volt (V)-compliance, making it ideal for robust industrial and white goods applications. TMP92FD23AFG/ADFG is a 32-bit MCU that incorporates 512 Kbytes of flash memory and 32 Kbytes of RAM, making it well suited for many industrial applications, such as vending machines and industrial control. Mask ROM versions of these devices are also available.

“Toshiba Corporation, a world leader in MCUs with one of the largest product portfolios available, has expanded its MCU product offering with these latest cost-effective 16- and 32-bit MCUs based on SuperFlash technology,” said Roland Gehrmann, business development manager in the ASSP Business Unit at TAEC. Since the company introduced its first 8-bit MCU with SuperFlash memory in April 2004, it has continued to roll out new devices that satisfy a wide range of applications.

The low-voltage, low-power consuming TMP91FW40FG 16-bit MCU combines 128 Kbytes of flash memory and 4 Kbytes of RAM with an anti-hypertensive-type LCD driver that can directly drive from 8 to 40 segments x 4 commons. The high-speed MCU is based on Toshiba’s ultra-low-power TLCS-900/L1 processor core and operates with voltages between 2.2V and 3.6V. The minimum instruction execution time is only 148 nanoseconds (ns) at 27 megahertz (MHz). Overall power consumption is further reduced by a dual clock and three standby modes, including a programmable idle option. It also offers an integrated 4-channel 10-bit analog-to-digital converter (ADC), a 4-channel 8-bit timer, a 3-channel 16-bit timer and a real-time clock with a calendar function. I/O functions include a 4-channel SIO/UART and 61 I/O ports. Packaging is a compact 100-pin LQFP package with dimensions of 14mm x 14mm with 0.50mm pitch. A mask ROM version (TMP91CW40FG) is also available.

The TMP91FW60FG/DFG 16-bit MCU combines 128 Kbytes of flash memory and 8 Kbytes of RAM. This low-power MCU is based on Toshiba’s TLCS-900/L1 processor core, and has operating voltage of 4.5V to 5.5V and a minimum instruction execution time of 200ns at 20MHz. It also provides an integrated 16-channel 10-bit ADC, a 6-channel 8-bit timer, a 5-channel 16-bit timer and a real-time counter. I/O functions include a 3-channel SIO/UART, 2-channel I2C/SIO and 83 I/O ports. As well, it incorporates 6 banks of program-patch logic. Packaging options consist of a 100-pin LQFP package with dimensions of 14mm x 14mm with 0.50mm pitch (TMP91FW60FG) or a 100-pin QFP package with dimensions of 14mm x 20mm with 0.65mm pitch (TMP91FW60DFG). A mask ROM version (TMP91CW60FG/DFG) is also available.

The TMP92FD23AFG/ADFG 32-bit MCU combines 512 Kbytes of flash memory and 32 Kbytes of RAM. The high-speed, high-performance MCU is based on Toshiba’s TLCS-900/H1 processor core and operates with voltages between 3.0V and 3.6V. The minimum instruction execution time is only 50ns at 20MHz. It also offers an integrated 12-channel 10-bit ADC, a 6-channel 8-bit timer, a 2-channel 16-bit timer and a real-time counter. I/O functions include a 3-channel SIO/UART (IrDA version 1.0 interface mode selectable), a 2-channel I2C interface, and 84 I/O ports. Additional on-board memory includes 4 Kbytes of mask ROM for booting; external memory expansion to 16 Mbytes is fully supported. Packaging options consist of a 100-pin P-LQFP package with dimensions of 14mm x 14mm with 0.50mm pitch (TMP92FD23AFG) or a 100-pin P-QFP package with dimensions of 14mm x 20mm with 0.65mm pitch (TMP92FD23ADFG). A mask ROM version (TMP92CY23FG/DFG) is equipped with 256 Kbytes of ROM and 16 Kbytes of RAM and has a built-in ROM correction function.

About Toshiba’s SuperFlash Implementation
Toshiba’s SuperFlash implementation can be programmed much faster than many alternative flash technologies. The availability of three distinct programming modes — parallel, serial PROM, and in-system programming (ISP) — provides pre- and post-production programming flexibility. ISP mode allows upgrades and fixes in the field under control of the user program. This removes the need to switch off the output to an LCD panel or active output controls.

Pricing and Availability
Samples of all of these devices are available now and they are in volume production. TMP91FW40FG is priced at $6.00 in 10,000-piece quantities, TMP91FW60FG is priced at 6.00 in 10,000-piece quantities, and TMP92FD23AFG is priced at $9.00 in 10,000-piece quantities.
