Description

The Microchip Technology Inc. 34AA04 is a 4 Kbit

Electrically Erasable PROM which utilizes the I

C serial

interface and is capable of operation across a broad

voltage range (1.7V to 3.6V). This device is JEDEC

JC42.4 (EE1004-v) Serial Presence Detect (SPD)

compliant and includes reversible software write

protection for each of four independent 128 x 8-bit

blocks. The device features a page write capability of

up to 16 bytes of data. Address pins allow up to eight

devices on the same bus.

The 34AA04 is available in the 8-lead PDIP, SOIC,

TSSOP, TDFN, and UDFN packages.

- Internally organized as two 256 x 8-bit banks

- Byte or page writes (up to 16 bytes)

- Byte or sequential reads within a single bank

- Self-timed write cycle (5 ms max.)

• JEDEC

JC42.4 (EE1004-v) Serial Presence

Detect (SPD) Compliant for DRAM (DDR4)

modules

• High-Speed I

C™ Interface:

- Industry standard 1 MHz, 400 kHz, and

100 kHz

- Schmitt Trigger inputs for noise suppression

- SMBus-compatible bus time out

• Write Protection:

- Reversible software write protection for four

individual 128-byte blocks

• Low-Power CMOS Technology:

- Voltage range: 1.7V to 3.6V

- Write current: 1.5 mA at 3.6V

- Read current: 200 µA at 3.6V, 400 kHz

- Standby current: 1 µA at 3.6V

• High Reliability:

- More than one million erase/write cycles

- Data retention: > 200 years

- ESD protection: > 4000V

• 8-lead PDIP, SOIC, TSSOP, TDFN, and UDFN
