Overview
The AT21CS01/AT21CS11 is a 2-pin memory (SI/O and Ground) that harvests energy from the SI/O pin to power the integrated circuit. It provides 1,024 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 128 words of eight bits each. The device is optimized to add configuration and use information in unpowered attachments using a two-point mechanical connection that brings only one signal (S|/O) and GND to the unpowered attachment. Some unpowered attachment application examples include analog sensor calibration data storage, ink and toner printer cartridge identification, and management of after-market consumables. The device's software addressing scheme allows up to eight devices to share a common single-wire bus. The device is available in space-saving package options and operates with an external pull-up voltage from 1.7V to 3.6V on the S|/O line (AT21CS01) or from 2.7V to 4.5V on the SI/O line (AT21CS11).
Applications
- Analog sensor calibration data storage
- Ink and toner printer cartridge identification
- Management of after-market consumables
Key features
- Low-Voltage Operation: AT21CS01 is self-powered via the 1.7V to 3.6V pull-up voltage on the S|/O line - AT21CS11 is self-powered via the 2.7V to 4.5V pull-up voltage on the SI/O line
- Internally Organized as 128x8 (1 Kbit)
- Industrial Temperature Range: -40℃ to +85℃
- Single-Wire Serial Interface with I²C Protocol Structure: - Device communication is achieved through a single I/O pin
- Standard Speed and High-Speed Mode Options: - 15.4 kbps maximum bit rate in Standard Speed mode (AT21CS01 only) - 125 kbps maximum bit rate in High-Speed mode (AT21CS01 and AT21CS11)
- 8-Byte Page Write or Single Byte Writes Allowed
- Discovery Response Feature for Quick Detection of Devices on the Bus
- ROM Zone Support: - Device is segmented into four 256-bit zones, each of which can be permanently made read-only (ROM)
- 256-Bit Security Register: - Lower eight bytes contain a factory-programmed, read-only, 64-bit serial number that is unique to all Microchip single-wire devices - Next eight bytes are reserved for future use and will read FFh - Upper 16 bytes are user-programmable and permanently lockable
- Self-Timed Write Cycle: 5 ms Maximum
- Manufacturer Identification Register: - Device responds with unique value for Microchip as well as density and revision information
- High Reliability: - Endurance: 1,000,000 write cycles - Data retention: 100 years - IEC 61000-4-2 Level 4 ESD Compliant (±8 kV Contact, ±15 kV Air Discharge)
- Green (Lead-free/Halide-free/RoHS Compliant) Package Options Die Sale Options: Wafer Form and Tape and Reel
