Summary
Preliminary
1. Description
The AT91FR40162S is a member of the Atmel AT91 16/32-bit Microcontroller family,
which is based on the ARM7TDMI processor core. The processor has a high-perfor-
mance 32-bit RISC architecture with a high-density 16-bit instruction set and very low
power consumption.
The AT91FR40162S ARM microcontroller features 2 Mbits of on-chip SRAM and 2
Mbytes of Flash memory in a single compact 121-ball BGA package. Its high level of
integration and very small footprint make the device ideal for space-constrained appli-
cations. The high-speed on-chip SRAM enables a performance of up to 74 MIPs in
typical conditions with significant power reduction and EMC improvement over an
external SRAM implementation.
The Flash memory may be programmed via the JTAG/ICE interface or the factory-
programmed Flash Memory Uploader (FMU) using a single device supply, making the
AT91FR40162S suitable for in-system programmable applications.
