1K-BIT SERIAL EEPROM WITH MICROWIRE INTEFACE
(compatible to САТ93С46 Catalyst)
DESCRIPTION
The IN93LC46 is a Electric erasable programmable ROM (EEPROM) memory data capac-
ity 1K (128x8 or 64x16) with 3-wire interface.
There are 3 modification of ICs
A: ICs IN93AA(LC)46AD/AN are 8 bits registers (128х8) - ORG pin is not used
B: ICs IN93AA(LC)46BD/BN are 16 bits registers (64х16) - ORG pin is not used
C: ICs IN93AA(LC)46CN/CD are configured as either registers of 8 bits (ORG pin at GND)
or 16 bits (ORG pin at VCC, or not connected). Each register can be written (or read) seri-
ally by using the DI (or DO) pin.
The ICs is purposed for reading, writing & nonvolatile data storage in electronic units with
3-wire interface. ICs can be used in TV-sets, telecom equipment & consumer electronic
devices.

Note
* this pin is present only in IN93AA46CN, IN93AA46CD:
When the ORG pin is connected to VCC, the x16 organization is selected.
When it is connected to ground, the x8 pin is selected.
If the ORG pin is left unconnected, then an internal pullup device will select the x16 organization.

EWEN/EWDS Instruction Timing
The IN93AA46/IN93LC46 powers up switch IC to the write disable state. Any writing after
power-up or after an EWDS (write disable) instruction must first be preceded by the EWEN
(write enable) instruction.
