Serial Flash Memory is a type of non-volatile memory that is commonly used to store data, program code, configuration settings, and other information in a wide range of electronic devices. It is called “serial” because data is read and written sequentially, typically using serial communication protocols like SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit).

Description

The EN25Q80A is an 8 Megabit (1024K-byte) Serial Flash memory, with advanced write protection
mechanisms. The EN25Q80A supports the standard Serial Peripheral Interface (SPI), and a high
performance Dual output as well as Quad I/O using SPI pins: Serial Clock, Chip Select, Serial DQ0(DI),
DQ1(DO), DQ2(WP#) and DQ3(NC). SPI clock frequencies of up to 80MHz are supported allowing
equivalent clock rates of 160MHz for Dual Output and 320MHz for Quad Output when using the
Dual/Quad Output Fast Read instructions. The memory can be programmed 1 to 256 bytes at a time,
using the Page Program instruction. […]

A Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of non-volatile memory that can store data even when the power is turned off. It is used in a wide range of electronic devices to store configuration settings, calibration data, and other small amounts of non-volatile information.

Part Number: 93C46

Function: 1K Microwire Serial EEPROM

Package: 8-lead MSOP and 6-lead SOT-23 Type

Manufacturer: Microchip Technology

Description

93C46 is 1K Microwire Serial EEPROM. The Microchip Technology Inc. 93AA46, 93LC46, 93C46, 93AA46A/B, 93LC46A/B & 93C46A/B are 1K low voltage serial Electrically Erasable PROMs (EEPROM). Generic memory devices such as the 93AA46, 93LC46 or 93C46 are dependent upon external logic levels driving the ORG pin to set word size. For dedicated 8-bit communication, the 93AA46A, 93LC46A or 93C46A devices are selected, while the 93AA46B, 93LC46B and 93C46B devices are selected for 16 bits. Advanced CMOS technology makes these devices ideal for low power, non-volatile memory applications. This 93XX Series is available in standard 8-lead MSOP and 6-lead SOT-23 packages.
