₹300.00
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.

The device’s cascadable feature allows up to four devices to share a common two-wire bus. The device is optimized for use in many industrial and commercial applications where lowpower and low-voltage operation are essential. The devices are available in spacesaving 8-pin PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead Leadless Array (LAP), and 8-lead SAP packages. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.
AT24C512 Datasheet
AT24C512C-SSHD
The AT24C512C functions as a slave device and communicates with a host controller, also known as the bus master, using a straightforward two-wire digital serial interface that is I2C-compatible. On a serial bus, the master initiates and manages all read and write operations to slave devices, and both the master and slave devices are capable of sending and receiving data. Just two signal lines?Serial Clock (SCL) and Serial Data?make up the serial interface (SDA). The bilateral SDA pin is used to receive command and detailed empirical from the master as well as to transmit data back to the master, while the SCL pin is used to accept the clock signal from the master. To reduce the impact of input spikes and bus noise, the SCL and SDA pins each include Schmitt Triggers and inbuilt spike suppression filters. The Most Significant bit (MSb) is always transmitted first when sending commands or data. After eight bits (one byte) of information have been exchanged during bus communication, the receiving device must answer with an Acknowledge (ACK) or No-Acknowledge (NACK) response bit during such a ninth clock cycle (ack/nack clock cycle) produced by the master. As a result, nine clock cycles are needed to send one byte of data. There must be no gaps or interruptions throughout any data transfer operation since there are no spare clock cycles.

No further erase cycle is necessary before Write since every programming cycle is fully self-timed. Programming one of the four blocks of write security into the status register activates block write protection. For added data security, separate instructions for programme enable and programme disable are given. The WP pin offers hardware data protection to guard against unintentional write attempts to the status register. Any serial communication can be halted using the HOLD pin without having to restart the serial sequence.
