MCP48CMD01-E/MF

Overview

The MCP48CMD01-E/MF is a single-channel, 8-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an SPI serial interface. It operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. The device provides buffered voltage outputs with selectable reference sources including VDD, external VREF, or an internal 1.214V bandgap. Key electrical parameters include a typical settling time of 4 µs, a gain error of ±0.6% of Full Scale Range (FSR), and an Integral Nonlinearity (INL) specification of ±1 LSB. It supports power-down modes and includes Power-on/Brown-out Reset protection.

Feature Summary

• Integrates MTP nonvolatile memory allowing user-programmable storage of DAC output values, configuration registers, and general-purpose data up to 32 times per location.
• Offers flexible voltage reference options supporting device VDD, external buffered/unbuffered inputs, or an internal bandgap source with selectable unity or two-times gain.
• Features a high-speed SPI-compatible serial interface capable of write speeds up to 50 MHz and read speeds up to 25 MHz.
• Includes WiperLock™ technology for synchronized updating of multiple DAC channels in dual configurations.

Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring persistent configuration data
• Low-power portable instrumentation
• PC peripherals and data acquisition systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure that the LAT/HVC pin voltage requirements are met during programming cycles if utilizing the nonvolatile memory features. Confirm compatibility with system voltage levels for both digital interfaces and analog references prior to integration.

Selection Notes

Select this component when a single-channel DAC with persistent memory is required without battery backup. Compare against volatile variants like the MCP48CVD01 if nonvolatile storage is unnecessary. Consider the MCP48CMD02 if dual-channel synchronization via WiperLock is needed. Verify that the 8-bit resolution meets the application's precision requirements compared to higher-resolution options in the family.

Part Context

This part belongs to the MCP48CXDX1/2 family of 8/10/12-bit DACs from Microchip Technology. The 'CMD' designation indicates the inclusion of MTP nonvolatile memory, distinguishing it from the 'CVD' volatile RAM counterparts. The '01' suffix specifies a single-channel output configuration, while 'MF' denotes the MSOP-10 package variant.

Replacement Considerations

For direct functional replacement with nonvolatile memory, consider the MCP48CMD01-E/UN (MSOP-10 tape/reel) or MCP48CMD01-E/ML (QFN-16). For volatile alternatives, the MCP48CVD01 series offers similar electrical characteristics without MTP capabilities. Dual-channel equivalents include the MCP48CMD02 series.
