Description
The AT91FR4042 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 AT91FR4042 ARM microcontroller features 2 Mbits of on-chip SRAM and 4 Mbits
of Flash memory in a single compact 121-ball BGA package. Its high level of integra-
tion and very small footprint make the device ideal for space-constrained applications.
The high-speed on-chip SRAM enables a performance of up to 63 MIPs and signifi-
cant power reduction over an external SRAM implementation.
The Flash memory may be programmed via the JTAG/ICE interface or the factory-pro-
grammed Flash Uploader using a single device supply, making the AT91FR4042
suitable for in-system programmable applications.
