1. Description
6257A–ATARM–20-Feb-08
The AT91SAM7L128/64 are low power members of Atmel’s Smart ARM Microcontroller family
based on the 32-bit ARM7
They also embed a large set of peripherals, including a Segment LCD Controller and a complete
set of system functions minimizing the number of external components.
These devices provide an ideal migration path for 8-bit microcontroller users looking for addi-
tional performance, extended memory and higher levels of system integration with strong
constraints on power consumption.
Featuring innovative power reduction modes and ultra-low-power operation, the
AT91SAM7L128/64 is tailored for battery operated applications such as calculators, toys,
remote controls, medical devices, mobile phone accessories and wireless sensors.
The embedded Flash memory can be programmed in-system via the JTAG-ICE interface or via
a parallel interface on a production programmer prior to mounting. Built-in lock bits and a secu-
rity bit protect the firmware from accidental overwrite and preserve its confidentiality.
The AT91SAM7L128/64 system controller includes a reset controller capable of managing the
power-on sequence of the microcontroller and the complete system. Correct device operation
can be monitored by a built-in brownout detector and a watchdog running off an integrated
oscillator.
By combining the ARM7TDMI processor with on-chip Flash and SRAM, and a wide range of
peripheral functions, including USART, SPI, External Bus Timer Counter, RTC and Analog-to-
Digital Converters on a monolithic chip, the AT91SAM7L128/64 microcontroller is a powerful
device that provides a flexible, cost-effective solution to many embedded control applications.
• AT91SAM7L128 features a 128 Kbyte high-speed Flash and a total of 6 Kbytes SRAM.
• AT91SAM7L64 features a 64 Kbyte high-speed Flash and a total of 6 Kbytes SRAM.
