New Series of 8-Bit Microcontrollers From Toshiba Incorporate Built-In Flash Memory
Blend of Flash Memory, High-Speed, Low-Power and Low-Voltage Operation Ideal for Wide-Ranging Portable Battery-Powered Applications
SAN JOSE, Calif., Feb. 18 /PRNewswire/ -- Toshiba America Electronic Components, Inc. (TAEC)* today announced the introduction of the first products in a new series of high-speed 8-bit microcontrollers (MCUs) suitable for portable battery-powered applications. Designated the TMP86FM48U and TMP86FM48F, the devices are among the industry's fastest 8-bit MCUs and are capable of operating at 8 megahertz (MHz) and 1.8 volts (V). Potential applications for the device range from portable digital consumer applications, such as portable compact disc players and other digital audio equipment, to irrigation control systems to electronic scales. Samples are scheduled to be available in March 2003 and volume production is slated to begin in May 2003.
"Toshiba Corporation, a world leader in both Flash technology and low-power, highly-integrated microcontrollers, is now enhancing its microcontroller product offering by introducing a series of new devices with on-board Flash memory. The new chips are among the fastest 8-bit MCUs available and are well-suited for many key market segments, including low-power, battery-operated digital consumer applications, audio applications, etc. Complete system development tools along with all necessary software packages are provided to meet the designers' needs," said Farhad Mafie, vice president of the ASSP Business Unit at TAEC.
The TMP86FM48U/F has 512 bytes of built-in data EEPROM, which can be put to such uses as backing up personality information at power-down, for instance, volume and presets in an audio system. The TMP86FM48U/F also incorporates Flash memory that can be programmed via the Universal Asynchronous Receiver Transmitter (UART), making it possible to program and reprogram the device easily after the chip has been mounted on a user board. This feature makes the TMP86FM48U/F ideal for a range of small-volume applications, as the basic board set can be customized on-demand by programming the Flash memory.
According to Don Schneider, business development manager of the ASSP Business Unit at TAEC, "The TMP86FM48U/F, with the ability to operate at 8MHz at 1.8V, combines Flash memory, data EEPROM and low power modes along with the timers, analog-to-digital (A/D) converters and UART required by many of today's portable applications."
Key Features
Key features of the microcontroller are as follows:
-- Low-voltage, high-speed operation is attained by combining the
Toshiba proprietary 8-bit microprocessor 870/C core and NAND-type
EEPROM. This feature makes the new microcontrollers ideal for
portable applications requiring low-voltage, high- speed operation.
Minimum instruction execution time is 500 nanoseconds at 1.8V,
8MHz.
-- 512 bytes of data EEPROM can be used for storing data when the
device is shut off. This feature makes the new microcontrollers
ideal for battery-driven portable audio equipment.
-- 32 Kbytes of built-in Flash memory for in-circuit programming allow
the device to be programmed via the UART after the product has been
mounted in the final application.
-- The power control function of the Flash circuitry turns off the
power to the Flash memory when it is not in use. This feature
allows an even lower operating current when operating in special
modes.
-- The Flash memory incorporates programmable security protection.
-- The microcontroller achieves the same level of low-power
consumption as Toshiba's mask ROM-based products.
-- On-chip peripherals include timers, an A/D converter, interrupt
sources, serial communication controllers and an LED driver.
Development Background
In recent years the portable applications market has seen a trend toward small-scale, diversified production. This trend has fuelled demand for microcontrollers with built-in Flash memory with performance comparable to their mask ROM counterparts. To respond to this demand, Toshiba has developed a new microcontroller series based on a high-speed TLCS-870/C CPU core. It incorporates NAND-type EEPROM that enables low-voltage drive and low-power consumption operation.
Pricing and Availability
Samples of TMP86FM48U/F are expected to be available in March 2003 at $6.67 per piece in 100-piece quantities. Volume production is scheduled to begin in May 2003 at an initial run rate of 100,000 units per month.
