Winbond Electronics Corporation America (WECA See Wi-Fi Alliance. ), a leading supplier of semiconductor solutions, today announced that it has introduced the W78E858. The chip is an 8051 EEPROM/PWM/Flash microcontroller aimed at consumer and industrial applications requiring non-volatile storage (storage) non-volatile storage - (NVS, persistent storage, memory) A term describing a storage device whose contents are preserved when its power is off. Storage using magnetic media (e.g. and Pulse Width Modulation See PWM. (PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a ) outputs in a single-chip solution. The IC is particularly well suited to applications needing re-programmable non-volatile data storage capability and digital-to-analog converter (DAC See D/A converter and discretionary access control.
DAC - Digital to Analog Converter ) functionality such as pay-per-view charges for entertainment systems, passwords for security systems, configuration information for industrial process controllers and fan speed control for thermal management systems. The chip is currently available in volume quantities and is priced at $4.00 U.S. in 1,000 unit quantities.
The W78E858 features 128 bytes of EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. with 100,000 write/erase cycles, four PWM output channels with 256 resolutions and 32K bytes of Flash memory for application code and 4K bytes of Flash memory for In-System-Programming code. The chip's superior EEPROM memory cell endurance provides extended write/erase cycles, allowing the chip to be programmed over and over. The chip also offers both byte-write and page-write modes with self-timed write, enabling designers to easily update the EEPROM. The non-volatile nature of EEPROM provides a permanent form of storage, even in the event of system power loss. The multiple PWM channels are ideal for low-cost digital-to-analog conversion. Both frequency and duty-cycle of the channel outputs are programmable and the 32K byte Flash memory provides ample code space for the application. In addition, the 4K byte Flash memory stores the user defined, 'boot-code' for in-system programming to update the 32K byte Flash memory.
"A wide variety of industrial and consumer applications now require high endurance, non-volatile, re-programmable data storage in the form of passwords, device ID, configuration data, etc.," said Larry Gaddy, director of product marketing, WECA. "The W78E858 single chip EEPROM/PWM/Flash microcontroller is a low-cost, feature-rich solution that economically addresses all of these needs."
Winbond Electronics Corporation was founded in 1987 and is based in Hsinchu Science-Based Park, Taiwan. It has since become the largest branded IC company in Taiwan, offering a broad range of PC and peripheral-related ICs, consumer electronics ICs, multimedia ICs, and memory ICs. Winbond is a market leader in the telephone dialer, PC I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output.
