The CAT25128 is a 128−Kb Serial CMOS EEPROM device internally organized as 16Kx8 bits. This features a 64−byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In addition, the required bus signals are clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial communication with the CAT25128 device. The device featuressoftware and hardware write protection, including partial as well as full array protection.

SPI(Serial Peripheral Interface,串行外圍接口)是Motorola公司提出的外圍接口協(xié)議,它采用一個(gè)串行、同步、全雙工的通信方式,解決了微處理器和外設(shè)之間的串行通信問題,并且可以和多個(gè)外設(shè)直接通信,具有配置靈活,結(jié)構(gòu)簡單等優(yōu)點(diǎn)。根據(jù)全功能SPI總線的特點(diǎn),設(shè)計(jì)的SPI接口可以最大發(fā)送和接收16位數(shù)據(jù);在主模式和從模式下SPI模塊的時(shí)鐘頻率最大可以達(dá)到系統(tǒng)時(shí)鐘的1/4,并且在主模式下可以提供具有四種不同相位和極性的時(shí)鐘供從模塊選擇;可以同時(shí)進(jìn)行發(fā)送和接收操作,擁有中斷標(biāo)志位和溢出中斷標(biāo)志位。

Enhanced version of the Serial Peripheral Interface available on Motorola s MC68HC11 family of CPUs.Enhancements include a wider supported operating frequency range, 4deep read and write fifos, and programmable transfer count dependent interrupt generation. As with the SPI found in MC68HC11 processors the core features programmable clock phase [CPHA] and clock polarity [CPOL]. The core features an 8bit wishbone interface. Very simple, very small.
