ATMEL AT91SAM7SE512 AT91SAM7SE256 AT91SAM7SE32 DATA SHEET
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.
