AT89C2051-24PU 8051 89C Microcontroller IC 8-Bit 24MHz 2KB (2K x 8) FLASH

Description

The AT89C2051 is a low-voltage, high-performance CMOS 8-bit microcomputer with

2K bytes of Flash programmable and erasable read-only memory (PEROM). The

device is manufactured using Atmel’s high-density nonvolatile memory technology

and is compatible with the industry-standard MCS-51 instruction set. By combining a

versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C2051 is a power-

ful microcomputer which provides a highly-flexible and cost-effective solution to many

embedded control applications.

The AT89C2051 provides the following standard features: 2K bytes of Flash, 128

bytes of RAM, 15 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt

architecture, a full duplex serial port, a precision analog comparator, on-chip oscillator

and clock circuitry. In addition, the AT89C2051 is designed with static logic for opera-

tion down to zero frequency and supports two software selectable power saving

modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial

port and interrupt system to continue functioning. The power-down mode saves the

RAM contents but freezes the oscillator disabling all other chip functions until the next

hardware reset.

Koben Electronics was founded in 1995 and is located in the Silicon Valley of China, Shenzhen. 

The mission of Koben has always been to provide quality electronics components to manufacturers worldwide. Early on we became a primary conduit for end-of-program and overstock inventory for major distributors such as Future Electronics and contract manufacturers as Flextronics. Koben has since then added sourcing of high quality components from local manufacturers in China.

Koben has always been customer driven rather than opportunity driven. Meaning- we will always choose path that is best for long term relationship with customer over short term view. It is why we have one of the highest customer retention scores of China based distributors.
