Microchip Technology AT91M55800A-33CI is an ARM7®-based 16/32-bit microcontroller operating at 33MHz. This ROMless device features 8KB of RAM and lacks program memory, requiring external program storage. Key peripherals include Power-on Reset (POR) and Watchdog Timer (WDT). Connectivity options are extensive, supporting EBI/EMI, SPI, and UART/USART interfaces. Data conversion capabilities are provided by an 8-channel 10-bit Analog-to-Digital converter and a 2-channel 10-bit Digital-to-Analog converter. With 58 I/O pins and a 176-BGA (13x13) package, this component is suitable for surface mounting. The operating temperature range is -40°C to 85°C. This device finds application in industrial automation, consumer electronics, and telecommunications equipment.
