Application Notes:
The Microchip Technology Inc. 24LC21A 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,
sending a serial bit stream of the memory array from 00h
to 7Fh, clocked by the VCLK pin. A valid high-to-low
transition on the SCL pin 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
24LC21A is available in a standard 8-pin PDIP and
SOIC package in industrial temperature range.
- Single Supply with Operation Down to 2.5V
- Completely Implements DDC1™/DDC2™ Interface for Monitor Identification, Including Recovery to DDC1
- Pin and Function Compatible with 24LC21
- Low-Power CMOS Technology
- 2-Wire Serial Interface Bus, I2C™ Compatible
- 100 kHz (2.5V) and 400 kHz (5V) Compatibility
- Self-Timed Write Cycle (including auto-erase)
- Page Write Buffer for up to Eight Bytes
- 1,000,000 Erase/Write Cycles Ensured
- Data Retention > 200 years
