The 93LC66A-E/P is a highly-reliable byte-wide serial EEPROM that utilizes the popular 8-pin PDIP package associated with EEPROMs. Our 93LC66A-E/P serial EEPROM is a non-volatile memory device that can be erased and reprogrammed without the exchange of external components. It incorporates Atmel’s high performance 8-bit AVR® microcontroller technology, providing an unparalleled combination of performance, cost and feature integration.

This 93LC66A-E/P belongs to the memory classification as it is a non-volatile memory device capable of storing digital data in perpetuity. It is commonly used in applications such as automotive systems, tools for home use, warehouse security and automation, remote control and data logging. The 93LC66A-E/P provides the basis for reliable a wired or wireless data storage solutions.

The 93LC66A-E/P works on the principles of read, write and erase cycles on the device. Read is best referred to as the process of data being sent back from the EEPROM to the host, usually a microcontroller. Write means that data is sent to the EEPROM so that it is written into the memory. Erase behaves similarly to data write but this is used when data is cleared from the EEPROM.

The 93LC66A-E/P consists of a 2K-bit memory array stored in an 8-pin PDIP package. This memory array can be divided into two separate 1K chunks, with each chunk storing 512 bits of data according to the manufacturer’s specifications. The EEPROM can be read and written to by connecting the device pins to the power source and ground.

These devices provide an improved performance in terms of endurance, data retention and high-temperature operation, making them ideal for use in a variety of automotive, consumer and industrial applications. EEPROMs such as the 93LC66A-E/P are specified with an operating temperature range of -40°C to +85°C and rated for an endurance of 1 million write/erase cycles.

The 93LC66A-E/P also includes an onboard special feature called the Selective Block Write which can be used to write data in blocks. This feature helps keep the cost down by reducing the number of write cycles required for data conversion. This feature allows the user to write data in select blocks rather than the entire memory array all at once.

The 93LC66A-E/P also features a low active power dissipation of 0.2 mA and a Standby current of 0.01µA, making it a very energy-efficient memory device. This device also provides a standby power connection for external power sources, allowing the user to monitor their device’s power consumption.

The 93LC66A-E/P is designed on open drain Totem-Pole technology and its compatible with both TTL and CMOS logic. It also supports a 2-wire Serial Interface. The device utilizes sequence commands for communications, enabling a continuous stream of data to be both read and written to the device in a single transaction.

Overall, the 93LC66A-E/P is one of the most reliable bytes-wide serial EEPROMs available on the market. With the added Selective Block Write feature, the device provides an economical solution to a range of application fields and user requirements.
