The AT91SAM7X256C-CUR embedded microcontroller is an 8-bit microcontroller designed by Atmel and runs on an ARM processor. It has two integrated timers, two QSPI serial ports, TPI (Trace Port Interface) for debugging, two 10-bit A/D converters and up to 61 programmable I/O lines. The AT91SAM7X256C-CUR is specifically designed for low-power applications that require extended battery life, low-power consumption and ultra-high reliability. It is available in 44-pin and 64-pin configurations with 256KB of FLASH and 32KB of SRAM.

The AT91SAM7X256C-CUR is suitable for various embedded applications, such as communications, automotive, medical, industrial control, and consumer electronics. It is designed to be compliant with the latest Ethernet, USB, and CAN standards to facilitate its integration into existing networks. Additionally, its high instruction throughput allows it to process complex algorithms in real time.

The AT91SAM7X256C-CUR has an embedded ARM7TDMI-S processor, which is a 32-bit RISC processor with a reduced instruction set and a Harvard architecture. The ARM7TDMI-S core can achieve up to 40 MIPs (million instructions per second) with a clock frequency of 30-54 MHz. It has an integrated Real-Time Clock (RTC) and an array of digital signal processor (DSP) instructions for efficient digital signal processing.

The AT91SAM7X256C-CUR features two integrated timers for general and advanced timer operations. The general timer can operate as an 8/16 bit timer, with programmable prescaler, interrupts, and various modes. The advanced timer is a timer/counter module with programmable period register, interrupt, compare, and dead-time comparators. Its integrated TPI (Trace Port Interface) enables embedded debugging and programming. Additionally, its two 10-bit A/D converters can be used to measure analog signals, and its 61 programmable I/O pins can be used to connect sensors and other external components.

The AT91SAM7X256C-CUR is programmed using Atmel\'s AVR Studio 5 software and is shipped with Atmel\'s own ARM development kit that includes the Atmel AVR Toolchain software and the Atmel SAM-ICE (In-Circuit Emulator). The SAM-ICE supports the AVRISP (Integrated Serial Programmer) protocol, allowing the user to program the device without removing it from the circuit. Moreover, it supports Atmel\'s SAM simulator, allowing developers to simulate the microcontroller\'s operations. The AT91SAM7X256C-CUR is available in a very small 44-pin LFCSP (leadframe chip-scale package) and a 64-pin AA-LGA-PBGA (accelerated assembly lead-free grid array, PBGA) package, both of which are designed to reduce board space and reduce power consumption.

In summary, the AT91SAM7X256C-CUR embedded microcontroller is an 8-bit microcontroller designed for low-power applications that require extended battery life and ultra-high reliability. It features an ARM7TDMI-S processor, two integrated timers, two 10-bit A/D converters, TPI (Trace Port Interface), and up to 61 programmable I/O lines. It is suitable for various embedded applications, such as communications, automotive, medical, industrial control, and consumer electronics. It is programmed with Atmel\'s AVR Studio 5 software and shipped with Atmel\'s own ARM development kit. It is available in 44-pin and 64-pin configurations with 256KB of FLASH and 32KB of SRAM.
