Atmel launches first 8-bit high-speed MCU [Copy link]

Atmel recently launched a high-speed, low-power AVR microcontroller AT76C713, suitable for low-cost USB applications.

AT76C713 is the first AVR microcontroller that can reach 48MHz. It is equipped with a full-speed USB driver interface; compatible with USB 2.0 specifications; and supports systems that need to communicate with peripherals through standard USB. AT76C713 integrates 16Kbytes of SRAM and 4 2Kbytes of SRAM storage, which are used for code debugging and data, cache, etc. In addition, according to the requirements of actual applications, 3 or more SRAM storage banks can be used for program code storage other than 16Kbytes SRAM. This performance greatly improves the configurability of the system.

USB compatible with boot ROM (read-only memory) can achieve counting and downloading by using descriptor parameters stored in peripheral EEPROM, data flash, Atmel-specific hard-wired USB descriptors, etc., saving the cost of permanent memory. AT76C713 provides a large number of I/O pins to support multiple functions, such as expandable data storage interface, input interrupt pin, output compare counter, etc. The UART module supports bidirectional FIFOs, one of which supports IrDA communication.

In order to facilitate user customization of AT76C713 functions, a development kit AT76C713-DK was released together with the AT76C713 sample product to assist in downloading and firmware updates. The AT76C713-DK is available directly from Atmel. The AT76C713-JT100 is packaged in a 100-pin lead-free, ROHS-compatible TQFP package, and the reference price for 10K quantities is $4.00.
