The SST89E5xxRD2 and SST89V5xxRD2 are FlashFlex51 family 8-bit microcontroller devices designed and manufactured using SST's unique and proprietary Super Flash CMOS semiconductor manufacturing technology. SST's clients gain significantly from the split-gate device structure and thick-oxide tunnelling injector in terms of cost and reliability. The devices are pin-for-pin compatible with ordinary 8051 microcontroller devices and use the 8051 instruction set. The devices include 16/24/40/72 K Byte of on-chip flash EEPROM programme memory that is divided into two separate programme memory blocks. The primary Block 0 has 8/16/32/64K Bytes of internal programme memory space, whereas the secondary Block 1 has 8K Bytes of internal programme memory space. The 8-KByte secondary block can be identified to the minimum address point in the 8/16/32/64 K Byte address space, as well as concealed from the programme counter and utilised as an independent EEPROM-like data store. In addition to the on-chip EEPROM programme memory of 16/24/40/72 K Bytes, the devices may address up to 64 K Bytes of external programme memory. In addition to 1024 x 8 bits of on-chip RAM, external RAM of up to 64 K Bytes may be addressed.

The 1024/2048/4096/8192/16384 bits of serial electrically erasable and programmable read-only memory (EEPROM) provided by the AT24C01A/02/04/08A/16A are structured as 128/256/512/1024/2048 words of 8 bits each. The gadget is designed with a variety of industrial and business applications in mind, where low-power and low-voltage functioning are crucial. The AT24C01A/02/04/08A/16A is accessible through a Two-wire serial interface and is offered in compact 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead MAP, 5-lead SOT23 (AT24C01A/AT24C02/AT24C04), 8-lead TSSOP, and 8-ball dBGA2 packages.

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.
