₹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.

25AA320-I/SN
The Microchip Technology Inc. 25AA320/25LC320/25C320 (25XX320*) serial Electrically Erasable PROMs are 32 Kbit. A basic Serial Peripheral Interface (SPI) compliant serial bus is used to access the memory. A clock input (SCK) is required, as well as separate data in (SI) and data out (SO) lines. A Chip Selection (CS) input controls access to the device. The hold pin allows you to suspend communication with the gadget (HOLD). Transitions on the device's inputs will be ignored while it is stopped, excluding Chip Select, enabling the host to service higher priority interrupts.

89E516RD2
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.
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.
