The document describes a microcontroller product based on the 80C51 core architecture, which features 256 bytes of on-chip RAM, 2048 bytes of on-chip ERAM, and 64K bytes of on-chip flash memory. Additionally, the product includes a boot code section with independent lock bits, 2K bytes of on-chip flash for a bootloader, in-system programming capability through an on-chip UART boot program and IAP, and 2K bytes of on-chip EEPROM. The product also incorporates an integrated power monitor, 14 sources of 4-level interrupts, three 16-bit timers/counters, a full duplex UART compatible with 80C51, a high-speed architecture, five ports, a five-channel 16-bit PCA with PWM, high-speed output, and timer and edge capture functionality. Other features include a double data pointer, a 21-bit watchdog timer, a 10-bit resolution analog to digital converter with 8 multiplexed inputs, SPI interface (PLCC52 and VPFP64 packages only), on-chip emulation logic, and power-saving modes such as idle mode and power-down mode.

A/T89C51AC2 is a high-performance Flash version of the 80C51 single chip 8-bit microcontrollers. It features 256 bytes of internal RAM and 32 KB of flash memory. It has various features including timers/counters, UART, PWM, and analog-to-digital converter.

The AT89C55WD is a low-power, high-performance CMOS 8-bit microcontroller with 20K bytes of Flash programmable read only memory and 256 bytes of RAM. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry standard 80C51 and 80C52 instruction set and pinout. The on-chip Flash allows the program memory to be user programmed by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C55WD is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications. The AT89C55WD provides the following standard features: 20K bytes of Flash, 256 bytes of RAM, 32 I/O lines, three 16-bit timer/counters, a six-vector, two-level interrupt architecture, a full-duplex serial port, on-chip oscillator, and clock circuitry. In addition, the AT89C55WD also provides power management unit and low power modes, which further reduce the system power consumption.

The AT89C51RC is a low-power, high-performance CMOS 8-bit microcontroller with 32K bytes of reprogrammable flash memory and 512 bytes of RAM. It is manufactured using Atmel's high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 and 80C52 instruction set and pinout. The on-chip flash allows user programming of the program memory using a conventional nonvolatile memory programmer. The AT89C51RC has 512 bytes of internal RAM available. The 256-byte expanded internal RAM is accessed via MOVX instructions after clearing bit 1 in the SFR located at address 8EH. The other 256-byte RAM segment is accessed the same way as the Atmel AT89-series and other 8052-compatible products. By combining a versatile 8-bit CPU with flash on a monolithic chip, the Atmel AT89C51RC provides a highly flexible and cost-effective solution.
