The AT21CS01-STUM10-T is a 1-Kbit (128 x 8-bit) single-wire serial EEPROM manufactured by Microchip using an I2C protocol architecture that supports both standard
speed (15.4 kbps) and high-speed (125 kbps) modes. It only needs two pins to operate: SI/O and GND. The SI/O signal is a combination of data and power lines that
provide power to the device, using a parasitic power supply scheme. The AT21CS01-STUM10-T device consists of 128 words with 8 bits each and is optimized for use in consumer and
industrial applications where reliable non-volatile storage is required. In addition, it has a 256-bit security register, including a unique 64-bit serial number.
AT21CS01-STUM10-T Features:
- 128 x 8 (1 Kbit) storage capacity
- Supports the I²C protocol
- Self-timed erase and write cycles, up to 5 milliseconds
- Communication via a single I/O pin
- Support standard speed (15.4 kbps) and high speed (125 kbps) modes
- The typical reading current is 0.08 mA, and the maximum reading current is 0.3 mA
- The typical write current is 0.2 mA and the maximum is 0.5 mA
- The typical value of standby current is 0.7 uA, and the maximum value is 2.5 uA
- Provides data retention for more than 1 million years
- ESD protection over 8000V (HBM)
AT21CS01-STUM10-T Application:
This EEPROM provides a flexible data storage solution, especially for applications that require data to be maintained without the use of power. The AT21CS01-STUM10-T
can be used in a variety of applications, including but not limited to:
· Analog sensor calibration data storage.
· Identification of ink cartridges and toner printers.
· Manage aftermarket consumables.
· Other situations where small amounts of non-volatile storage are required.
