Microchip Technology, Inc. Microcontrollers AT89C5131-TISIL

The AT89C5131-TISIL is an 8-bit microcontroller featuring an 80C52X2 core capable of operating at a maximum frequency of 48 MHz in X1 mode and 24 MHz in X2 mode. It includes 32 KB of on-chip Flash memory, 256 bytes of scratchpad RAM, and 1024 bytes of expanded RAM (ERAM). The device supports full-duplex enhanced UART communication and is equipped with three 16-bit timer/counters, a programmable counter array (PCA), and a hardware watchdog timer. This microcontroller integrates a USB 1.1 and 2.0 compliant module with multiple endpoints for versatile data transfer, including control, bulk, interrupt, and isochronous transfers. It features a low power voltage range of 3.0V to 3.6V, with a maximum operating current of 30 mA at 40 MHz and a power-down current of 100 µA. The AT89C5131-TISIL is suitable for applications requiring industrial temperature range operation and is available in a 28-lead SOIC package.
