LE2416RLBXA
CMOS IC
Two Wire Serial Interface
EEPROM (16k EEPROM)
Overview
The LE2416RLBXA is a 2-wire serial interface EEPROM. It realizes high speed and a high level reliability by
incorporating SANYO’s high performance CMOS EEPROM technology. This device is compatible with I2C memory
protocol; therefore it is best suited for application that requires small-scale re-writable nonvolatile parameter memory.
Functions
Capacity: 16k bits (2k × 8 bits)
Single supply voltage: 1.7V to 3.6V (to read)
Operating temperature: -40 to +85ºC
Interface: Two wire serial interface (I2C Bus*)
Operating clock frequency: 400kHz
Low power consumption
: Standby: 2μA (max)
: Active (Read): 0.5mA (max)
Automatic page write mode: 16 Bytes
Read mode: Sequential read and random read
Erase/Write cycles: 105 cycles (Page write)
Data Retention: 20 years
Pull-up resistance: 5k(Typ.) on WP pin with a built-in pull-up resister
High reliability: Adopts SANYO’s proprietary symmetric memory array configuration (USP6947325)
Noise filters connected to SCL and SDA pins
Incorporates a feature to prohibit write operations under low voltage conditions.
Package : WLFCP6(0.80 × 1.20)

Pin Functions
SCL (serial clock input) pin
The SCL pin is a serial clock input pin that processes signals at the rising and falling edges of SCL clock signals.
The SCL pin must be pulled up by a resistor to the VDD level and wired-ORed with an open drain (or open collector)
output device for use.
SDA (serial data input/output) pin
The SDA pin is used to transfer serial data to the input/output, and it consists of a signal input pin and n-channel
transistor open drain output pin.
Like the SCL pin, the SDA pin must be pulled up by a resistor to the VDD level and wired-ORed with an open drain
(or open collector) output device for use.
WP (write protect) pin
When the WP pin is high, write protection is enabled, and writing into the 16k bit memory areas is prohibited. When
the pin is low, writing is possible to all memory areas. Read operations can be performed regardless of the WP pin
status.
It is resistance (Typ. 5k) between WP to VDD2
VDD2 (Power supply for WP pin) pin
VDD2 pin is for the pull-up power supply to WP pin. Voltage impression of -0.5 to VDD+0.5V is permitted like other
pins about the pin voltage.

5) Noise filter for the SCL and SDA pins
This product contains a filter circuit for eliminating noise at the SCL and SDA pins. Pulses of 100ns or less are not
recognized because of this function.
6) Function to inhibit writing when supply voltage is low
This product contains a supply voltage monitoring circuit that inhibits inadvertent writing below the guaranteed
operating supply voltage range. The data is protected by ensuring that write operations are not started at voltages
(typ.) of 1.3V and below.
