The document describes an ARM processor with internal high-speed flash, featuring high performance, high-density instruction set, and low power consumption. It also includes 512 KB or 256 KB of internal high-speed SRAM, supports an external bus interface, and has memory and reset controllers.
The AT91SAM7SE series microcontrollers integrate an ARM7TDMI® core with high‑speed Flash memory, SRAM, and a rich set of peripherals such as USB 2.0 device, External Bus Interface, USART, SPI, TWI, ADC, PWM and timers. The devices are offered in three memory configurations: 512 KB Flash/32 KB SRAM (AT91SAM7SE512), 256 KB Flash/32 KB SRAM (AT91SAM7SE256) and 32 KB Flash/8 KB SRAM (AT91SAM7SE32). They support a wide voltage range and can operate up to 55 MHz.
The datasheet includes detailed block diagrams, signal descriptions, electrical and mechanical characteristics, ordering information, and errata. Package options are 128‑lead LQFP and 144‑ball LEBGA, both RoHS‑compliant. The document is intended for hardware designers and system integrators needing precise electrical parameters and pin‑level details.
