Application Notes:
The Microchip Technology Inc. 24LCS21A is a
128 x 8-bit dual-mode Electrically Erasable PROM.
This device is designed for use in applications
requiring storage and serial transmission of configuration
and control information. Two modes of operation
have been implemented: Transmit-Only mode and
Bidirectional mode. Upon power-up, the device will be
in the Transmit-Only mode, a valid high-to-low transition on the SCLpin will cause the device to enter the Transition mode and look for a valid control byte on the I2C™Compatible bus. If it
detects a valid control byte from the master, it will switch into Bidirectional mode, with byte selectable read/write capability of the memory array using SCL.
If no control byte is received, the device will revert to
the Transmit-Only mode after it receives 128 consecutive
VCLK pulses while the SCL pin is idle. The
24LCS21A also enables the user to write-protect the
entire memory array using its write-protect pin. The
24LCS21A is available in a standard 8-pin PDIP and
SOIC package in industrial temperature range.
- Single Supply with Operation Down to 2.5V

- Low-Power CMOS Technology: - 1 mA active current, typical - 10 uA standby current, typical at 5.5V
- 2-Wire Serial Interface Bus, I2C™ Compatible
- 100 kHz (2.5V) and 400 kHz (5V) Compatibility
- Self-Timed Write Cycle (including Auto-Erase)
- Hardware Write-Protect Pin
- Page Write Buffer for up to Eight Bytes
- 1,000,000 Erase/Write Cycles Ensured
- Data Retention > 200 years
- ESD Protection > 4000V
- 8-pin PDIP and SOIC Package
- Available for Extended Temperature Ranges: - Industrial (I): -40°C to +70°C
- Pb-Free and RoHS Compliant
