Microchip Currently Brought into Service a Single-Wire EEPROM for Remote Identification


Microchip
Semiconductor manufacturing company Microchip recently introduced a new Serial EEPROM. This new device is able to utilize a bus that is single-wired using only 2 pins in accessing the device: SI/O and GRN. SI/O, which is the 1st pin, features a line that integrates power and data, This provides the needed power towards the device and also to the management of the data.

The AT21CS11 is arranged as one block in the dimensions of 128x8. It may be used in reliable memory storage applications that are non-volatile. The Serial EEPROM features a pre-programmed and unique serial number or ID as well as a one-hundred twenty-eight bit tracking number that is user-programmable. The voltage range for operation ranges from 2.7 volts to 4.5 volts. This voltage range makes the chip compatible for use with lithium-ion batteries.

The AT21CS11 makes identifying and tracking possible to any kind of product that is detachable or replaceable. This means that plastic disposables, cartridges, and user-specific attachments can relay unique identification details and also utilize information over a simple 2 point clip or connection that is plugged in. Additionally, the evaluation kit, which is dedicated by Microchip for the AT21CSxx, supports this new device (it is a single-wire family).

The AT21CS11 has many great features. It is one Kbit, features a single-wire compatibility, has the potential of communicating through one, possess’ a single I/O pin, has a high-speed mode of 125 kbps and attributes self-rimed erase and write cycles. The chip also attributes low power consumption (it’s read current is 0.8 mA, write current is 0.2 mA, and it’s standby current 0.7 uA). It boasts software write protection, includes more than one-million erase and write cycles, and factory programming is available.
