Features

Description

• 4 Kbit/16 Kbit SRAM with EEPROM Backup:

The

Microchip

Technology

Inc.

47L04/47C04/47L16/47C16 (47XXX) is a 4/16 Kbit

SRAM with EEPROM backup. The device is organized

as 512 x 8 bits or 2,048 x 8 bits of memory and utilizes

the I²C serial interface. The 47XXX provides infinite

read and write cycles to the SRAM while EEPROM

cells provide high-endurance nonvolatile storage of

data. With an external capacitor, SRAM data is

automatically transferred to the EEPROM upon loss of

power. Data can also be transferred manually by using

either the Hardware Store pin or software control.

Upon power-up, the EEPROM data is automatically

recalled to the SRAM. Recall can also be initiated

through software control.

- Internally organized as 512 x 8 bits (47X04)

or 2,048 x 8 bits (47X16)

- Automatic Store to EEPROM array upon

power-down (using optional external

capacitor)

- Automatic Recall to SRAM array upon

power-up

- Hardware Store pin for manual Store

operations

- Software commands for initiating Store and

Recall operations

- Store time 8 ms maximum (47X04) or

25 ms maximum (47X16)

• Nonvolatile External Event Detect Flag

• High Reliability:

- Infinite read and write cycles to SRAM

- More than one million store cycles to

EEPROM

- Data retention: >200 years

- ESD protection: >4,000V

• High-Speed I²C Interface:

Packages available

• 8-Lead PDIP

• 8-Lead SOIC

• 8-Lead TSSOP

Package Types

- Industry standard 100 kHz, 400 kHz and

1 MHz

- Zero cycle delay reads and writes

- Schmitt Trigger inputs for noise suppression

- Cascadable up to four devices

• Write Protection:

• Low-Power CMOS Technology:

- 200 µA active current typical

- 40 µA standby current (maximum)

• Available Temperature Ranges:

- Industrial (I):

- Extended (E):

-40°C to +85°C

-40°C to +125°C
