Ce e 24LC21???

In dataheet nu am inteles mare lucru, dar cred ca e microcontroller, fiindca spunea de niste algoritmi si are emblema microchip pe el. Gresesc cumva?

Citez: 24LC21 is a 128 x 8 bit 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 entire memory array contents, clocked by the VCLK pin. A valid high-to-low transition on the SCL pin will cause the device to enter the Bidirectional mode, with byte selectable read/write capability of the memory array. The 24LC21 is available in a standard 8-pin PDIP and SOIC package, in both commercial and industrial temperature ranges.

 

Concluzia cred ca o poti trage si tu.

Sa vad daca am inteles. Chestia asta e un microcontroller care poate fi rescris?

Este vorba de un eprom, deci o memorie. Cel putin asta am inteles eu.

NU E MICROCONTROLER

 

e doar o memorie EEPROM I2C din seria 24Cxx.

se foloseste pentru stocarea informatiilor de configurare. banuiesc ca ai scos-o de pe o placa de monitor. la monitoare e folosita pentru stocarea datelor DDC. adica stocarea rezolutiilor si ratelor de refresh care le accepta monitorul. in momentul in care pornesti monitorul, aceasta memorie transmite date catre placa video a calculatorului pentru a stii ce rezolutii suporta monitorul.

plug&play.....

E de la un TV, nu de la un monitor.

Pot sa-i vad datele? Daca da, cum?
