CAT25040YI-GT3 詳細描述
Product Overview
The CAT25040YI-GT3 from onsemi is a non-volatile EEPROM memory IC offering 4Kbit of storage in an 8-TSSOP surface-mount package. It uses a serial peripheral interface and is specified for 20 MHz SPI operation. The memory is organized as 512 x 8 bits, and it operates from a 1.8 V to 5.5 V supply across an ambient temperature range of -40°C to +85°C (TA).
Key Features
- 4Kbit non-volatile EEPROM with a 512 x 8 organization.
- SPI serial memory interface specified for 20 MHz operation.
- 5 ms write cycle time for word or page writes.
- 1.8 V to 5.5 V supply voltage range.
- Surface-mount 8-TSSOP package, 0.173-inch / 4.40 mm width.
- Rated for -40°C to +85°C ambient operating temperature (TA).
Applications
- Retention of configuration data in microcontroller-based embedded systems.
- Storage of calibration values for sensor modules and measurement devices.
- Small lookup tables or parameter blocks in SPI-connected equipment.
Design & Procurement Notes
Design considerations should focus on SPI timing, host voltage compatibility, and the 5 ms write cycle when scheduling updates. The 1.8 V to 5.5 V supply range can be matched to host logic voltage, while the -40°C to +85°C (TA) range should be checked against the expected ambient environment. The 8-TSSOP surface-mount package requires a footprint compatible with the 0.173-inch / 4.40 mm body width, and the 4Kbit capacity is suited to small data sets rather than bulk storage. Firmware should allow write latency before verifying updated contents.
