| Toshiba Broadens Embedded Flash Microcontroller Product Line Toshiba America Electronic Components, Inc. has announced the expansion of its embedded flash microcontroller (MCU) product line with the addition of a new 16-bit MCU and six new 8-bit MCUs based on SuperFlash technology. The TMP91FY42FG, Toshiba's first 16-bit device with high-capacity SuperFlash memory, integrates 256Kbytes of flash memory and was designed for medium- to high-end applications, including industrial control, security systems and handheld products. Since the company introduced its first 8-bit MCU with SuperFlash memory in April 2004, it has continued to roll out new devices and with the addition of the latest devices, the family now consists of 19 MCUs targeting a wide range of applications, including consumer and industrial products. Highly Integrated TMP91FY42FG 16-Bit MCU Integrates 256Kbytes of On-Board Flash, Minimizes External Component Count and Enhances Programming Flexibility The TMP91FY42FG combines a high-capacity flash memory of 256Kbytes with an integrated 10-bit 8-channel analog-to-digital converter (ADC), an 8-channel 8- bit timer, a 2-channel 16-bit timer and a watchdog timer. I/O functions include a 2-channel SIO/UART, an I2C interface, support for IrDA version 1.0 at 115.2kbps, and 81 I/O ports. Additional on-board memory includes 16Kbytes of internal RAM and 4Kbytes of mask ROM for booting; external memory expansion to 16Mbytes is fully supported. The high-speed MCU is based on Toshiba's ultra-low-power TLCS-900/L1 processor core and operates with voltages between 2.7 volts (V) and 3.6V. The minimum instruction execution time is only 148 nanoseconds at 27 megahertz. Overall power consumption is further reduced by the three standby modes, including a programmable idle option. The device is fully compatible with other Toshiba devices based on the TLCS-900/L and TLCS- 900/H cores. Packaging is a compact 100-pin LQFP package with dimensions of 14mm x 14mm. The new 8-bit MCUs consist of 6 devices with flash memory configurations ranging from 16Kbytes to 60Kbytes and various RAM, peripheral and packaging options. Two of the devices incorporate an LCD controller for powering displays; this integration reduces external component count and increases reliability. The devices incorporate the high-performance Toshiba TLCS-870/C 8-bit CPU core. See the table below for a technical overview of the devices. 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. write your comments about the article :: © 2006 Computing News :: home page |
