NANTES, France--(BUSINESS WIRE)--May 15, 2001--Atmel® Corporation (Nasdaq:ATML) announced today the addition of a new 80C51 microcontroller to its FLASH microcontrollers portfolio, featuring 32-Kbyte FLASH memory with In-system Programming (ISP) capability and an embedded 8-channel 10-bit analog-to-digital converter (ADC), targeting market segments such as home appliances, industrial control, automotive comfort and climate control.

Based on the well known 80C51 architecture, the T89C51AC2 retains all the features of the Atmel TS8xC51Rx2 with 256 bytes of internal RAM plus 1024 bytes of XRAM. Three on-chip non-volatile memories are available: a 32-Kbyte FLASH program memory, a separate 2-Kbyte boot memory and a 2-Kbyte EEPROM for application parameter storage. Each of them can be programmed by byte or by block, either in parallel or in serial mode.

The T89C51AC2 offers a highly flexible In-system Programming capability through UART, using a standard five Volt supply, enabling system designers to load or update program without removing the device from the board.

Thanks to ISP, FLASH memory reconfiguration is possible even while the application is running, allowing remote diagnosis, upgrade and enhancements in the field.

Along with the rich combination of memory capacity, the T89C51AC2 contains a varied peripherals set including an advanced 8 channels 10-bit resolution A/D converter. The on-chip association of the A/D converter and 2-Kbytes of EEPROM allows the storage of calibration information (adjustement and gain), without the need for external components.

The T89C51AC2 supports a Programmable Counter Array (PCA), a hardware watchdog timer, power control modes, and also benefit from the high-speed core (X2 mode) which can double internal frequency for CPU and peripherals (upon selection).

Designed for a wide range of products, the T89C51AC2 is the powerful and easy-to-implement C51 microcontroller solution for all applications needing A/D conversion, pulse width modulation and high speed I/O.

Manish Vadher, Marketing Director for Standard Microcontrollers at Atmel Wireless and Microcontrollers Division said, ``On top of the well known advantages of a full ISP Flash microcontroller, the T89C51AC2 with its on-chip 10-bit ADC and extra 2-Kbyte EEPROM combined with the flexible 32-Kbyte FLASH ISP will provide customers greater integration and improve time-to-market. The product is well suited for a variety of applications including industrial control and automotive comfort control.''

Available in industrial temperature range, the device is packaged in 44-pin PLCC or 44-pin VQFP and operates at 40 MHz at 5 Volts.

Volume production and samples are available now. The T89C51AC2 costs $5.95 each for 1Kpcs.
