Architecture and Features

The AT89C51CC03C-SLRIM Microcontroller has a Harvard architecture with a 8052-compatible architecture. The 8052-compatibility means that existing 8052-source programs can be easily ported to the AT89C51CC03C-SLRIM. The device has 8KB of Flash program memory, 128 bytes of RAM, 16 I/O lines, five 16-bit timers/counters, three serial ports, and is ideal for applications that require digital data acquisition, efficient data communications, high resolution motor control, and advanced system monitoring. The device also features idle and power-down modes, watchdog timer, variable clock frequency, and power-on reset which provides a reliable wake-up from power-down modes.

Power Management

The AT89C51CC03C-SLRIM has a low power sleep mode, so it can be used in battery-powered applications to reduce power consumption. It also has a low-power idle mode, which is triggered when the CPU is idle and wakes up when the microcontroller is required to start performing instructions again. It also has a power down mode that reduces the power consumption to around 0.6mW while all internal RAM is retained, providing an effective power savings solution for battery-powered applications.

Programming and Interfacing

The AT89C51CC03C-SLRIM can be programmed using an external programmer or in-circuit emulator. It has several built in features to monitor and debug programs. It has 8051-compatible work development tools, which include assemblers, linkers, and debuggers that can be used to develop and debug applications in C or assembler language. It has on-chip ISP programming and debugging support, so it can be programmed or debugged via the serial port. It also has built-in I/O to facilitate connection to external devices, and various interfaces such as LCD, keypad, and other peripherals.
