Atmel 8-Bit Microcontroller, 2KB Flash, 20-Pin DIP

Atmel 8-bit microcontroller with 2KB Flash memory in a 20-pin Dual In-line Package (DIP) for embedded design. It combines an 8-bit CPU with on-board Flash memory on a single monolithic chip, which streamlines development and reduces system complexity.

Overview

The microcontroller is a CMOS device manufactured using Atmel's high-density non-volatile memory technology. It is fully compatible with the industry-standard MCS-51 instruction set and features a fully static design that allows operation from 0Hz up to 24MHz.

Key Features

• Core and memory: 8-bit CPU with 2KB of in-system reprogrammable Flash memory for program storage, plus 128 x 8-bit internal RAM
• I/O and peripherals: 15 programmable I/O lines, two 16-bit timer/counters, a programmable serial UART channel and six interrupt sources for handling real-time events
• On-chip features: analogue comparator and oscillator with clock circuitry, reducing the need for external components
• Operating range: 4V to 6V operating voltage, with a supply voltage capability from 2.7V to 6V, and an industrial temperature range from -40°C to 85°C
• Security and packaging: two-level program memory lock to secure code, supplied in a through-hole mountable 20-pin DIP package

Power Management

Two software-selectable power modes are available: Idle and Power Down. Power Down mode preserves RAM contents while halting the oscillator to minimise energy consumption until the next hardware reset, making it suitable for battery-powered applications.

Dimensions and Weight

Dimensions: width 3.3, depth 1.5 and height 4.3. Weight: 227.3 gm.

Applications

Suitable for prototyping and robust embedded systems, this 20-pin DIP microcontroller is well suited to embedded designs that require integrated memory, I/O and peripherals on one chip.
