Description
The M24M01-HR, M24M01-R and M24M01-W are I
programmable memory (EEPROM) devices organized as 128 Kb × 8 bits.
The I
line. The devices carry a built-in 4-bit device type identifier code (1010) in accordance with
the I
The M24M01-HR, M24M01-R and M24M01-W behave as slaves in the I
memory operations synchronized by the serial clock. Read and Write operations are
generated by the bus master and initiated by a Start condition, followed by the device select
code, address bytes and data bytes. Data transfers are terminated by a Stop condition after
an Ack for Write, and after a NoAck for Read.
When writing data to the memory, the device inserts an acknowledge bit during the 9
time, following the bus master’s 8-bit transmission. When data is read by the bus master, the
bus master acknowledges the receipt of the data byte in the same way.
The M24M01-HR, M24M01-R and M24M01-W are delivered in SO8 packages and the
M24M01-R is also available in wafer form (see
(package, voltage range, frequency, temperature grade)
As EEPROM cells loose their charge (and so their binary value) when exposed to ultra violet
(UV) light, EEPROM dice delivered in wafer form by STMicroelectronics must never be
exposed to UV light.
