Atmel Introduces a New 32-Kbyte In-system Programmable FLASH 80C51 8-bit Microcontroller With On-chip ADC.Business Editors/High-Tech Writers NANTES, France--(BUSINESS WIRE)--May 15, 2001 Atmel(R) Corporation (Nasdaq:ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ) 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 (1) See A/D converter. (2) (Apple Display Connector) A peripheral connector from Apple that combines digital video display, USB and power in one cable. ), 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 XRAM Extended Ram XRAM External Ram XRAM Exclusive or Memory . 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 (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. 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 (Universal Asynchronous Receiver Transmitter) The electronic circuit that makes up the serial port. Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice , 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 (tool, programming) PCA - A dynamic analyser from DEC giving information on run-time performance and code use. ), a hardware watchdog timer, power control modes, and also benefit from the high-speed core (X2 mode) which can double internal frequency for CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. 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 See PWM. 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 (Plastic Leaded Chip Carrier) A plastic, square, surface mount chip package that contains leads on all four sides. The leads (pins) extend down and back under and into tiny indentations in the housing. See chip package. or 44-pin VQFP VQFP Very Thin Quad Flat Package VQFP Very small Quad Flat Package VQFP very-fine-pitch quad flat pack and operates at 40 MHz at 5 Volts. Volume production and samples are available now. The T89C51AC2 costs $5.95 each for 1Kpcs.
