Atmel 8-Bit 8051 Flash MCU 64KB 44-Pin LCC SMD

Atmel 8-Bit 8051 Flash MCU 64KB is an 8-bit CMOS microcontroller with 64 KB of on-chip flash memory for both code and data, supplied in a 44-pin LCC surface-mount package.

Overview

The Atmel 8-bit 8051 flash MCU retains all the features of the standard 80C52 and is compatible with 8051 instructions. It provides 2048 bytes of EEPROM for non-volatile data storage and 1792 bytes of expanded RAM (XRAM). The flash memory can be programmed in parallel or serial mode using in-system programming (ISP) or via software, with the programming voltage generated internally from the standard VCC pin.

Key Features

• Integrated power monitor (POR/PFD) that supervises the internal power supply
• Programmable counter array and hardware watchdog timer
• SPI interface and keyboard interrupt interface
• Enhanced UART (EUART) with a dedicated internal baud rate generator for multiprocessor communication
• Dual data pointer and variable length MOVX for slow RAM and peripherals
• X2 mode for independent speed selection of the CPU and peripherals
• Low EMI mode (inhibit ALE) and idle and power-down power control modes

Specifications

• Operating frequency of up to 60 MHz
• Operating temperature range of -40°C to +85°C
• Supply voltage between 2.7 V and 5.5 V
• Dimensions of 43 mm x 33 mm x 15 mm (height x width x depth)
• Weight of 0.2 gm

Applications

Designed for demanding environments, this microcontroller suits industrial temperature range applications and surface-mount circuit board designs. Its combination of on-chip flash, EEPROM and expanded RAM allows code, data and non-volatile storage to be handled within a single device.

Choose the Atmel 8-Bit 8051 Flash MCU 64KB when a compact, 80C52 compatible microcontroller with integrated memory and serial communication is required.
