FT24C16A-UTG-T

Overview

The FT24C16A-UTG-T is a 16K-bit (2048 x 8) serial EEPROM from Fremont Micro Devices Ltd, housed in an 8-pin TSSOP package. It operates on a supply voltage of 1.8V to 5.5V with standby current under 1µA. The device supports I²C interfaces at up to 1 MHz (at 5V) or 400 kHz (at lower voltages). Key electrical parameters include a maximum write cycle time of 5ms and data retention of 100 years.

Feature Summary

• Supports 16-byte page write operations with partial page write capability.
• Includes hardware write protection via the WP pin for data security.
• Features Schmitt trigger inputs to filter noise and ensure signal integrity.
• Provides automatic erase-before-write functionality during programming cycles.

Applications

• Low power embedded systems requiring non-volatile storage
• Industrial control units operating within extended temperature ranges
• Consumer electronics utilizing standard two-wire serial interfaces

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'U' indicates the -40°C to 85°C industrial temperature range, 'T' confirms tape and reel packaging, and 'G' denotes RoHS compliance. Ensure the component source aligns with Fremont Micro Devices Ltd documentation to confirm authenticity and correct package type.

Selection Notes

Select this part when a single device per bus is acceptable, as the FT24C16A lacks address pins for multi-device selection. It is suitable for applications needing byte-alterable memory with low power consumption. Consider alternative series members if multiple devices must share the same serial bus line.

Part Context

This component belongs to the FT24C04A/08A/16A series of Two-Wire Serial EEPROMs. These devices utilize advanced CMOS technology for low voltage operation. The series shares common interface protocols and reliability standards, differing primarily in memory organization and available address pins for bus configuration.

FAQ

Can multiple FT24C16A devices be connected to the same I²C bus?

No, the FT24C16A does not use device address pins (A0-A2 are NC), allowing only one device per bus.

How does the Write Protect (WP) pin function?

Connecting WP to VCC disables all programming functions, while leaving it unconnected or at VIL allows write operations.
