Microchip Technology, Inc. Microcontrollers AT89S53-24JC

The AT89S53-24JC is an 8-bit microcontroller from Lingto Electronic Limited, featuring 12K bytes of in-system reprogrammable Flash memory. It operates within a voltage range of 4V to 6V and supports a maximum clock frequency of 24 MHz. The microcontroller is compatible with MCS-51 products and includes 256 bytes of internal RAM, 32 programmable I/O lines, and three 16-bit timer/counters. It also offers a programmable UART serial channel and a SPI serial interface for program downloading. The device is designed for low-power applications, featuring idle and power-down modes to conserve energy. It includes a programmable watchdog timer and supports interrupt recovery from power-down states. The AT89S53-24JC is suitable for various embedded control applications, although it is noted as not recommended for new designs, with a suggestion to consider the AT89S8253 instead.
