X9313ZM-3

Digital Potentiometers Overview

The X9313ZM-3 is a single-channel digital potentiometer IC from the X9313 series, manufactured by Renesas Electronics Corporation. It features a resistance value of 1 kOhm with 32 taps and utilizes a linear taper profile. The device employs a non-volatile memory architecture to retain wiper settings without power. It operates on a serial 3-wire interface and supports supply voltages between 3 V and 5.5 V. The component is housed in an 8-lead MSOP package and is designed for surface-mount installation.

Digital Potentiometers Feature Summary

• Single digital potentiometer with 1 kOhm total resistance and 32 adjustable taps
• Non-volatile memory retains wiper position after power loss
• Serial 3-wire interface (U/D, INC, CS) for control
• Linear taper characteristic with ±20% tolerance

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference setting in measurement systems
• Calibration of sensor bias points

Digital Potentiometers Procurement Notes

Verify the specific suffix 'Z' against official Renesas documentation to confirm if it denotes a specific tape-and-reel packaging variant or environmental compliance status distinct from the standard tube packaging. Confirm RoHS compliance details directly from the manufacturer's datasheet before procurement.

Digital Potentiometers Selection Notes

Select this component when a low-resistance (1 kOhm) digital potentiometer with non-volatile storage is required. Ensure the application voltage does not exceed 5.5 V. Verify that the 3-wire serial interface is compatible with the host microcontroller's available GPIOs or SPI controller.

Digital Potentiometers Part Context

The X9313ZM-3 belongs to the X9313 family of CMOS EEPOTs. This family typically includes variants with different resistance values such as 10 kOhm and 50 kOhm. The 'ZM' designation generally indicates the MSOP-8 package type within the Renesas product line.

Digital Potentiometers Replacement Considerations

The X9313UMZ-3 is listed as a direct replacement for the discontinued X9313UM-3. However, the X9313UMZ-3 has a 50 kOhm resistance value, whereas the X9313ZM-3 is 1 kOhm. Direct substitution requires verifying if the circuit tolerates the resistance difference.
