Microchip Technology's 24AA08HT-I/OT: A High-Temperature Serial EEPROM

The 24AA08HT-I/OT is a versatile and robust 8-Kb Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) chip designed and manufactured by Microchip Technology. This high-temperature, high-performance memory device is ideal for a wide range of applications that require data storage under extreme operating conditions.

With its I2C-compatible (2-wire) serial interface, the 24AA08HT-I/OT provides a simple and efficient method for data communication. The device supports a standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) I2C protocol, making it suitable for various microcontroller interfacing requirements.

One of the standout features of the 24AA08HT-I/OT is its ability to operate over an extended temperature range of -40°C to +125°C. This makes it an excellent choice for automotive and industrial environments where reliability and durability are critical under high-temperature conditions.

The memory is organized as four blocks of 256 x 8-bit memory, allowing for flexible data storage options. Additionally, the 24AA08HT-I/OT offers a write-protect feature that prevents accidental data overwriting, thus ensuring the integrity of the stored information.

With a low standby current and a low active read current, the device is energy-efficient, making it suitable for battery-operated and power-sensitive applications. Furthermore, the 24AA08HT-I/OT comes in a small SOT-23 package, which is ideal for space-constrained applications where board real estate is at a premium.

Key features of the 24AA08HT-I/OT include:

• 8-Kb (1K x 8) memory size
• Extended temperature range: -40°C to +125°C
• I2C serial interface with standard, fast, and high-speed modes
• Write-protect feature for data security
• Low power consumption
• Compact SOT-23 package

Whether you're developing automotive electronics, industrial control systems, or any application that requires reliable data storage under harsh conditions, the 24AA08HT-I/OT from Microchip Technology is a smart choice that combines performance with resilience.
