24LC16BHT-I/SN

Memory IC Overview

The Microchip Technology 24LC16BHT-I/SN is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I²C protocols. The device operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. It includes hardware write protection for half the array, Schmitt trigger inputs for noise suppression, and output slope control. The component is rated for industrial temperatures from -40°C to +85°C and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Hardware write protection allows selective inhibition of write operations for the upper half of the memory array when the WP pin is tied high.
• Schmitt trigger inputs and filter circuits suppress noise spikes on the SCL and SDA lines to ensure reliable operation in noisy environments.
• Output slope control minimizes ground bounce effects during signal transitions, maintaining signal integrity on the bus.

Memory IC Applications

• Embedded systems requiring non-volatile data storage with I²C connectivity
• Industrial control units needing hardware-level write protection for critical parameters
• Low-power consumer electronics operating on single-supply voltages

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds specifically to the 8-lead SOIC package type. Confirm the 'I' designation matches the required industrial temperature range of -40°C to +85°C. Ensure the 'T' indicates tape-and-reel packaging if automated assembly is planned. Cross-reference the full part number against the manufacturer's current datasheet to confirm active status and any recent design changes.

Memory IC Selection Notes

Select this component when a 16-Kbit EEPROM with I²C compatibility is required alongside specific hardware write protection capabilities. The 24LC16BH series distinguishes itself by protecting only the upper half of the memory array (addresses 400h-7FFh) via the WP pin, unlike other variants that may protect different sections or none. Ensure the system voltage remains above 2.5V to meet the specified operational requirements for this specific sub-family.

Memory IC Part Context

This part belongs to the 24XX16H family of 16-Kbit serial EEPROMs manufactured by Microchip Technology. The 'BH' suffix denotes the low-voltage variant optimized for 2.5V to 5.5V operation, distinct from the 1.7V-capable 24AA16H or 24FC16H models. The 'I' indicates industrial temperature grading, while 'SN' specifies the plastic small outline package.

Memory IC FAQ

How does the hardware write protection function on the 24LC16BHT-I/SN?

Connecting the WP pin to VCC inhibits write operations for the upper half of the memory array (addresses 400h through 7FFh). Read operations remain unaffected regardless of the WP pin state. Tying WP to VSS enables write access to the entire memory space.

What is the maximum clock frequency supported by this device?

The device supports a maximum clock frequency of 400 kHz when operating within the 2.5V to 5.5V supply voltage range.
