Embest ATEBSAM7S Evaluation Board
- A Complete Evaluation Kits for Atmel AT91SAM7S64 ARM7TDMI Microcontrollers
- Expands all HW interfaces associated with the AT91SAM7S64
- Plenty of software examples, all in source code
Embest ATEBSAM7S evaluation board
The 32-bit AT91SAM7S64 is based on a 1.8V ARM7TDMI core operating at up to 55 MHz. It features an integrated 64K byte flash and a 16K byte high-speed on-chip SRAM and is an ideal migration path for 8-bit microcontroller users looking for additional performance and extended memory. Support flash Encryption techniques and could protect the firmware from accidental overwrite and preserves its confidentiality. Together with a wide range of peripherals including ADC, USART, USB, SPI, TWI, PWM and 32 GPIO adapting for various controls is designed for users to apply in various aspects including industrial automotion, medical and any other general purpose embedded application requiring high lever of integration and a aggressive price point.
Embest ATEBSAM7S™ Evaluation Board is an evaluation board expands all function circuits of AT91SAM7S64 microcontroller, and supports additional peripheral hardware which includes an 8-segment LED, push-button interface, buzzer and ADC. With ATEBSAM7S board, users can easily evaluate the AT91SAM7S64 microcontroller, begin code development on the target hardware using the board as a solid reference design. The Embest ATEBSAM7S Evaluation Board kits is a complete evaluation environment. It contains a development board, a JTAG debugger interface, and a suite of software tools for embedded development.
