AT89C5131A-L is a high-performance Flash version of the 80C51 single-chip 8-bit microcontrollers with full speed USB functions.

AT89C5131A-L retains the features of the Atmel 80C52 with extended Flash capacity (32-Kbyte), 256 bytes of internal RAM, a 4-level interrupt system, two 16-bit timer/counters (T0/T1), a full duplex enhanced UART (EUART) and an on-chip oscillator.

In addition, AT89C5131A-L has an on-chip expanded RAM of 1024 bytes (ERAM), a
dual- data pointer, a 16-bit up/down Timer (T2), a Programmable Counter Array (PCA), up to 4 programmable LED current sources, a programmable hardware watchdog and a power-on reset.

AT89C5131A-L has two software-selectable modes of reduced activity for further reduction in power consumption. In the idle mode the CPU is frozen while the timers, the serial ports and the interrupt system are still operating. In the power-down mode the RAM is saved, the peripheral clock is frozen, but the device has full wake-up capability through USB events or external interrupts.
