24LC21AT規(guī)格書詳情

24LC21AT屬于集成電路(IC)的存儲(chǔ)器。由微芯科技股份有限公司制造生產(chǎn)的24LC21AT存儲(chǔ)器存儲(chǔ)器是集成電路上用作數(shù)據(jù)存儲(chǔ)設(shè)備的半導(dǎo)體器件。這些器件分為非易失性或易失性兩種,格式包括 CBRAM、DRAM、EEPROM、EERAM、EPROM、閃存、FRAM、NVSRAM、PCM (PRAM)、PSRAM、RAM 和 SRAM。這些器件的存儲(chǔ)容量為 64 b 至 6 Tb 不等,接口有 I2C、MMC、并行、eMMC、串行、單線、SPI、UFS、Xccela 總線和 1-線。

描述 Description

The Microchip Technology Inc. 24LC21A is a 128 x 8-bit dual-mode Electrically Erasable PROM. This device is designed for use in applications requiring storage and serial transmission of configuration and control information. Two modes of operation have been implemented:

Transmit-only mode and Bidirectional mode. Upon power-up, the device will be in the Transmit-only mode, sending a serial bit stream of the memory array from 00h to 7Fh, clocked by the VCLK pin. A valid high-to-low transition on the SCL pin will cause the device to enter the transition mode, and look for a valid control byte on the I2C bus. If it detects a valid control byte from the master, it will switch into Bidirectional mode, with byte selectable read/write capability of the memory array using SCL. If no control byte is received, the device will revert to the Transmit-only mode after it receives 128 consecutive VCLK pulses while the SCL pin is idle. The 24LC21A is available in a standard 8-pin PDIP and SOIC package in both commercial and industrial temperature ranges.
