DESCRIPTION
The M2201 is a simplified 2-wire bus 1 Kbit electri-
cally erasable programmable memory (EEPROM),
organized as 128 x8 bits. It is manufactured in
STMicroelectronics鈥檚 Hi-Endurance Advanced
CMOS technology which guarantees a data reten-
tion of 100 years at 55擄C.
The M2201 is available in Plastic Dual-in-Line,
Plastic Small Outline and Thin Shrink Small Out-
line packages.
The memory is compatible with a two wire serial
interface which uses a bi-directional data bus and
serial clock. Read and write operations are initi-
ated by a START condition generated by the bus
master and ended by a STOP condition.
Address bits and RW bit are defined in one single
byte, instead of two (or three) bytes for the standard
I
2
C protocol.
