Atmel Introduces a New 16- & 32-Kbyte In-system Programmable FLASH 80C51 8-bit Microcontrollers.Business Editors/High-Tech Writers NANTES, France--(BUSINESS WIRE)--March 27, 2001 Atmel(R) Corporation (Nasdaq:ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ) announced today the expansion of its FLASH microcontrollers offering by adding two new 80C51 microcontrollers, featuring up to 32-Kbyte FLASH memory with a highly flexible In-system Programming (ISP (1) See in-system programmable. (2) (Internet Service Provider) An organization that provides access to the Internet. Connection to the user is provided via dial-up, ISDN, cable, DSL and T1/T3 lines. ) capability. The T89C51RB2 with 16-Kbyte Flash and the T89C51RC2 with 32-Kbyte Flash are based on the well known 80C51 architecture and support 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 . The on-chip FLASH memory with boot loader can be programmed by byte or by block, either in parallel or in serial mode. Both devices offer easy-to-implement In-system Programming capability either 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 or SPI serial communication interfaces, using standard 3 or 5 Volts supply. The program can be loaded or updated without removing the device from the board, providing a significant flexibility to system designers. With ISP even flash program memory can be reconfigured while the application is running, allowing remote diagnosis, upgrade and enhancements in the field. The T89C51RB2 and the T89C51RC2 feature 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 take advantage of 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). According to Manish Vadher, Marketing Director for Standard Microcontrollers at Atmel Wireless and Microcontrollers Division, "These new products offer designers a unique opportunity to accelerate system integration. They have a medium size FLASH memory, easy to implement In-system Programming through multi-serial interfaces and large RAM capacity fully adapted for C-language programming. These features are suitable for a wide range of applications such as alarms, TFT LCD monitors, set top box, Internet appliances and smart card readers." Plug-in compatible ROM T83C51RB2 and T83C51RC2 versions are also available to cut down manufacturing costs. "Beyond cost, we understand that lead-time is also a critical factor when it comes to purchasing. Compared to traditional ROM suppliers' commitment, our mask ROM service offers reduced lead-times to enable production at high volumes," continues Manish Vadher. Available in industrial temperature range, the devices are packaged in 40-pin DIL, 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 . They operate at 40 MHz at 5 Volts and 20 MHz at 3 Volts. Volume production and samples are available now. The Flash version T89C51RB2 costs $3.30 each for 1Kpcs and the ROM version T83C51RB2 costs $1.60 each for quantities above 30Kpcs.
