Microchip Technology, Inc. Embedded - Embedded - Microcontrollers - AT89C51RB2-SLSIM AT89C51RB2-SLSIM

The AT89C51RB2-SLSIM is an 8-bit microcontroller featuring 16KB of on-chip Flash memory and 1024 bytes of expanded RAM (XRAM). It is compatible with the 80C52 architecture, providing four 8-bit I/O ports, three 16-bit timer/counters, and a 9-source interrupt controller with four priority levels. The device supports in-system programming (ISP) and offers a high-speed architecture with operation speeds of up to 40 MHz in standard mode and 20 MHz in X2 mode, depending on the supply voltage. This microcontroller includes a programmable counter array, a full duplex enhanced UART with a dedicated baud rate generator, and a keyboard interrupt interface. It operates within a supply voltage range of 2.7V to 5.5V and is available in a PLCC44 package suitable for industrial applications with a temperature range of -40¬8C to +85¬8C. The AT89C51RB2-SLSIM is designed for applications requiring efficient power management, featuring idle and power-down modes to reduce power consumption. Its capabilities make it suitable for various applications, including motor control and communication devices.
