Microchip Technology's SST89V554RC-40-I-PI is an 8-bit microcontroller built around the robust 8051 CPU core. This device features 32KB of on-chip FLASH program memory and 40KB of data EEPROM, alongside 1KB of SRAM. Operating at a maximum frequency of 40MHz, it supports essential communication interfaces including SPI and UART, and offers 32 general-purpose I/O lines. The microcontroller includes three timers, watchdog timer (WDT), brown-out detection (BOD), and power-on reset (POR) peripherals. Designed for industrial applications, it operates within a temperature range of -40°C to +85°C and requires a supply voltage of 3.3V, with a maximum current draw of 88mA. The component is housed in a 40-pin PDIP package, suitable for through-hole mounting.
