The MCP9843 and MCP98243 are JEDEC-compliant digital temperature sensors designed for accurate temperature monitoring in memory modules, industrial electronics, communication equipment, and other high-reliability applications.
The MCP9843 complies with JC42.4-TSE3000B3, while the MCP98243 complies with JC42.4-TSE2002B3 and integrates a 2 Kbit serial EEPROM for Serial Presence Detect (SPD) applications.
These devices feature a 2-wire I2C/SMBus interface, allowing easy connection to MCUs, processors, and system controllers. The simple interface reduces PCB routing complexity and supports efficient communication in compact electronic designs.
With multiple package options including DFN-8, TDFN-8, UDFN-8, and TSSOP-8, the devices can meet different PCB layout and assembly requirements. This flexibility makes them suitable for both space-constrained designs and standard industrial applications.
The built-in temperature-to-digital converter provides direct digital temperature output, eliminating the need for external analog conversion circuitry. This helps simplify system design, reduce component count, and improve overall reliability.
In terms of accuracy, the sensor offers strong performance under Grade B specifications.
Typical and maximum accuracy are as follows:
±0.2°C / ±1°C from +75°C to +95°C
±0.5°C / ±2°C from +40°C to +125°C
±1°C / ±3°C from -20°C to +125°C
This high level of accuracy makes the device ideal for temperature-sensitive systems such as memory modules, power management systems, industrial controllers, and networking equipment.
For voltage compatibility, the device supports a wide operating range.
The temperature sensor section has a specified VDD range of 3.0V to 3.6V, with an operating VDD range of 2.7V to 5.5V.
The EEPROM section supports a specified VDD range of 1.8V to 5.5V, making the device suitable for various power system designs.
Low power consumption is another important advantage.
The temperature sensor operates at only 200 µA typical current, making it suitable for energy-efficient and long-running systems.
For the EEPROM function, the typical current is:
Write: 1.1 mA typical for 3.5 ms typical
Read: 100 µA typical
The MCP98243 includes a 2 Kbit serial EEPROM, organized as 1 block of 256 x 8-bit memory. This memory can be used to store SPD data, configuration settings, calibration values, and other important system information.
To improve data security, the device supports permanent and reversible software write protection, as well as software write protection for the lower 1 Kbit. This helps prevent accidental overwriting of critical data and improves long-term system reliability.
Overall, the MCP9843 and MCP98243 combine JEDEC compliance, high accuracy, low power consumption, flexible voltage support, and compact package options. The MCP98243 further adds integrated EEPROM and write protection, making it an excellent choice for applications requiring both temperature monitoring and data storage.
