... Automotive (E): -40°C to +125°C DESCRIPTION The Microchip Technology Inc. 24C01C bit Serial Electrically Erasable PROM with a voltage range of 4.5V to 5.5V. The device is organized as a single block of 128 x 8-bit memory with a 2-wire serial inter- face. Low current design permits operation with typical standby and active currents of only 10 µ ...

This terminates the write operation, but not before the internal address pointer is set. Then the master issues the control byte again but with the R/W bit set to a one. The 24C01C will then issue an acknowledge and transmits the eight bit data word ...
