Detailed Description for CAT34C02YI-GT5A
Product Overview
The CAT34C02YI-GT5A from onsemi is an 8-TSSOP EEPROM memory IC for nonvolatile storage in surface-mount embedded designs. It provides 2Kbit of memory organized as 256 x 8 and communicates over an I2C interface with a 400 kHz clock frequency. The device operates from a 1.7V to 5.5V supply and is rated for an ambient temperature range of -40°C to 85°C. It offers a 900 ns access time and a 5 ms word or page write cycle time, supporting small-capacity settings, identifiers, or calibration data retention.
Key Features
- Nonvolatile EEPROM memory with a 2Kbit capacity and 256 x 8 organization.
- I2C serial interface supporting a 400 kHz clock frequency.
- 900 ns access time.
- 5 ms word or page write cycle time.
- 1.7V to 5.5V supply voltage range.
- -40°C to 85°C operating temperature range (TA).
- 8-TSSOP package with 0.173 in (4.40 mm) width.
- Surface-mount mounting type for compact PCB assembly.
- EEPROM technology for retention of stored data when power is removed.
Applications
- Embedded control boards storing device configuration parameters that must remain available after power cycling.
- Small instrumentation modules retaining calibration coefficients or measurement offsets in nonvolatile memory.
- Equipment boards holding serial numbers, asset identifiers, or user preference data.
- Host controllers using a low-capacity I2C memory for lookup tables or status records.
Design & Procurement Notes
Design considerations should center on the 1.7V to 5.5V supply range, the 400 kHz I2C clock limit, and the 5 ms write cycle time. The 900 ns access time and 256 x 8 organization define how much data can be addressed and how quickly the device can be accessed. The 8-TSSOP footprint and surface-mount mounting type require appropriate pad layout and assembly handling. The -40°C to 85°C ambient operating range should be checked against the expected board environment. For procurement, confirm that the package dimensions and electrical parameters match the selected board design and host interface. Because the memory capacity is 2Kbit, the part is suited to small data records rather than bulk storage.
