Description

The 25LC160A-I/SN is one member of the 25LC160A series.It has the following features including (1)low-power CMOS technology;(2)2048 x 8-bit organization;(3)self-timed ERASE and WRITE cycles;(4)block write protection-Protect none, 1/4, 1/2 or all of array.

The Microchip Technology Inc. 25LC160A-I/SN are 16 Kbit Serial Electrically Erasable PROMs. The memory is accessed via a simple Serial Peripheral Interface™ (SPI™) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to 25LC160A-I/SN is controlled through a Chip Select (CS) input.Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of chip select, allowing the host to service higher priority interrupts.The 25LC160A-I/SN is available in standard packages including 8-lead PDIP and SOIC, and advanced packaging including 8-lead MSOP, and 8-lead TSSOP. Pb-free (Pure Matte Sn) finish is also available.Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for an extended period of time may affect device reliability.

The 25LC160A-I/SN are 2048 byte Serial EEPROMs designed to interface directly with the Serial Peripheral Interface (SPI) port of many of today's popular microcontroller families, including Microchip's PICmicro® microcontrollers. It may also interface with microcontrollers that do not have a built-in SPI port by using discrete I/O lines programmed properly with the software.The device is selected by pulling CS low. The 8-bit read instruction is transmitted to the 25XX160A followed by the 16-bit address, with the five MSBs of the address being don't care bits. After the correct read instruction and address are sent, the data stored in the memory at the selected address is shifted out on the SO pin. The data stored in the memory at the next address can be read sequentially by continuing to provide clock pulses. The internal address pointer is automatically incremented to the next higher address after each byte of data is shifted out.
