AT24CO2

A 4K x 8 (32K bit) Serial Electrically Erasable PROM is the 24C32. This gadget was created for high-end, low-power uses like data collecting or personal communications. The 24C32 has an input cache with a capacity of eight 8-byte pages, or 64 bytes, allowing quick write loads. Additionally, it has a fixed 4K-bit block of ultra-high endurance memory for regularly changing data. Up to the 32K border, the 24C32 may read both randomly and sequentially. Up to eight 24C32 devices can share a bus with functional address lines, providing a maximum address space of 256K bits. This device is perfect for moderate POWER??non-volatile code and data applications thanks to advanced CMOS technology. The typical 8-pin plastic DIP and 8-pin surface mount SOIC packaging for the 24C32 are also available.   Features:- ?

A CMOS 8-bit microcontroller with 20K bytes of Flash programmable read-only memory and 256 bytes of RAM, the AT89C55WD is a low-power, high-performance device. The product is made using high-density flash storage technology from Atmel and has pinout and an instruction set that comply with industry standards 80C51 and 80C52. An ordinary nonvolatile memory programmer can user programme the programme memory thanks to the on-chip Flash. The Atmel AT89C55WD is a potent microcomputer that offers a very flexible and area of business to many embedded control applications by mixing a flexible 8-bit CPU with Flash on a monolithic chip. The following features are included as standard with the AT89C55WD: A full-duplex serial port, an on-chip oscillator, clock circuitry, three 16-bit timer/counters, 32 I/O lines, 256 bytes of RAM, 20K bytes of Flash, and a six-vector, two-level interrupt architecture. The AT89C55WD also features two software-selectable power-saving modes and static logic allowing operating down to zero frequency. The CPU is turned off in idle mode, but the RAM, timers and counters, serial port, and interruption system are still operational. The oscillator is frozen in the Power-down Mode, which also disables all other chip operations until the next error detection or device reset. However, the RAM contents are saved.
