CY7C148集成电路（IC）的存储器规格书PDF中文资料

CY7C148属于集成电路（IC）的存储器。由赛普拉斯半导体公司制造生产的CY7C148存储器存储器是集成电路上用作数据存储设备的半导体器件。这些器件分为非易失性或易失性两种，格式包括 CBRAM、DRAM、EEPROM、EERAM、EPROM、闪存、FRAM、NVSRAM、PCM (PRAM)、PSRAM、RAM 和 SRAM。这些器件的存储容量为 64 b 至 6 Tb 不等，接口有 I2C、MMC、并行、eMMC、串行、单线、SPI、UFS、Xccela 总线和 1-线。

Functional Description

The CY7C148 and CY7C149 are high-performance CMOS static RAMs organized as 1024 by 4 bits. Easy memory expansion is provided by an active LOW chip select (CS) input and three-state outputs. The CY7C148 remains in a low-power mode as long as the device remains unselected; i.e., (CS) is HIGH, thus reducing the average power requirements of the device. The chip select (CS) of the CY7C149 does not affect the power dissipation of the device.
