NEW
8-BIT OTP MICROCONTROLLER FROM TOSHIBA CONTROLS SMALL ELECTRIC HOME
APPLIANCES
Compact 8MHz MCU Has Optimal Feature Set for Space-Constrained Designs
SAN
JOSE, Calif.,
February 26, 2003 -- Toshiba America Electronic Components, Inc.
(TAEC)* today announced the introduction of a new 8-bit microcontroller
(MCU) that provides an optimal solution for system control of small
electric home appliances. The chip integrates a high-performance
8-bit CPU core with on-board memory in a compact 20-pin Dual In-line
Package (DIP) small enough for size-sensitive appliance designs.
Samples are available now with volume production scheduled to start
in March 2003.
"Toshiba
Corporation, a world leader in microcontrollers and non-volatile
memory, is now enhancing its microcontroller product offering by
introducing a new low-cost One-Time-Programmable (OTP) microcontroller
that can operate at 8 megahertz (MHz). Toshiba continues to see
growth in the low-end microcontroller market as 8-bit MCUs proliferate
in high-volume, small electric home appliance applications," said
Farhad Mafie, vice president of the ASSP Business Unit at TAEC.
The
device comes in two versions: the TMP86P202P supports a ceramic
or crystal resonator and the TMP86P203P supports a resistance-capacitance
(RC) resonator. Each of these microcontrollers incorporates 2 Kbytes
of OTP memory and 128 bytes of Random Access Memory (RAM). Each
MCU includes two channels of 8-bit timer/counter and four channels
of 8-bit analog-to-digital (A/D) converter, ideally suited for control
of small electric home appliances such as irons, crock pots and
electric shavers.
According
to Don Schneider, business development manager of the ASSP Business
Unit at TAEC, "The TMP86P202/3P MCUs are targeted at small appliance
designs that require a minimal peripheral set that includes A/D
converters in combination with quick production turn-around time
and low cost."
Key
Features
Key features of the MCU are as follows:
- High-speed
operation of 8MHz at 4.5V is attained in the TMP86P202P
by combining the Toshiba proprietary 8-bit microprocessor
870/C core with compact OTP. The result is a microcontroller
ideal for small home appliances where high-speed is crucial.
- The
TMP86P202P supports either a ceramic or crystal resonator
while the TMP86P203P supports an external RC resonator.
The latter version offers further system cost reductions
for applications that do not require timer precision.
- Built-in
OTP enables end product manufacturers to perform programming,
thus contributing to faster timer-to-market. This feature
also facilitates small-lot, diversified applications.
- Housed
in a space-saving 20-pin DIP, the chip can be easily mounted
on a user board.

Development
Background
Toshiba developed the new 8-bit MCU in response to growing demand
for low-cost, high-performance MCUs in the small home electric appliances
market. Based on a high-performance 8-bit CPU core, the new device
uses OTP as program Read Only Memory (ROM), which improves turnaround
time from application development to product launch. Other distinguishing
features include low price and compact size, which are attained by
the optimization of functions.
Pricing and Availability
Samples of TMP86P202P and TMP86P203P are available now at $1.67
per piece in 100 piece quantities. Volume production is scheduled
to begin in March 2003.
