Product details
Overview
MCP47CMB01-E/UN from Microchip Technology is a single-channel, 8-bit nonvolatile memory DAC with I²C interface, ±0.1 LSb integral nonlinearity, 16 µs settling time, and operation from 2.7V to 5.5V - used for precision sensor calibration and set-point trimming in industrial control modules.
For engineers reviewing the MCP47CMB01-E/UN datasheet, MCP47CMB01-E/UN pinout, MCP47CMB01-E/UN application, or MCP47CMB01-E/UN equivalent, key selection criteria include nonvolatile MTP programming capability (32 cycles), dual reference options (VDD/internal bandgap/external VREF), 1x/2x output gain, power-down modes with selectable pull-down resistors, and extended temperature support (–40°C to +125°C).
Technical Context
The MCP47CMB01-E/UN implements an R-2R resistor ladder architecture with buffered voltage output and internal op-amp gain control. It supports three reference sources - device VDD, external VREF (buffered/unbuffered), or internal 1.214 V bandgap - with programmable 1x or 2x output gain when VREF is used.
Its I²C interface operates at Standard (100 kHz), Fast (400 kHz), or High-Speed (up to 3.4 MHz) modes, using two address-select pins (A0/A1) for slave addressing. Nonvolatile memory includes DAC power-up values, configuration registers, and 8 general-purpose MTP locations, each writable up to 32 times via 7.5 V on the LAT/HVC pin.
Key Specifications

Use Value: High-speed I²C (3.4 Mbps) enables rapid brightness/volume updates; 10-lead compact package saves PCB area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP47CVB01-E/UN | Volatile RAM only (no MTP); identical pinout, resolution, and interface | Lacks persistent power-up value storage - requires host MCU initialization at boot | Select when calibration data is managed externally or updated frequently in-system |
| DAC8560IDGKR | 16-bit resolution, SPI interface, no internal reference; higher precision but larger footprint (8-pin VSSOP) | Targeted at high-accuracy data acquisition, not embedded calibration | Choose only if 16-bit resolution and SPI compatibility outweigh size, cost, and reference integration needs |
Compared with MCP47CVB01-E/UN, the MCP47CMB01-E/UN adds field-programmable nonvolatile storage without changing layout or firmware interface; versus DAC8560IDGKR, it trades resolution and interface flexibility for smaller size, lower cost, and integrated reference - making it optimal for space-constrained embedded calibration.

FAQ
What is the maximum operating voltage for MCP47CMB01-E/UN?
The MCP47CMB01-E/UN supports a supply voltage range of 2.7 V to 5.5 V for full specifications. Operation down to 1.8 V is permitted but results in reduced analog performance. Absolute maximum rating is 6.5 V on VDD relative to VSS; exceeding this risks permanent damage. The MCP47CMB01-E/UN must never be operated above 6.5 V, even transiently.
How many times can the nonvolatile memory of MCP47CMB01-E/UN be programmed?
The MCP47CMB01-E/UN supports up to 32 write cycles per nonvolatile memory location. After the 32nd write, further programming attempts are ignored and the stored value remains unchanged. This endurance applies to all MTP locations - including DAC power-up value, configuration registers, and the eight general-purpose locations. The MCP47CMB01-E/UN requires 7.5 V on the LAT/HVC pin to initiate each write cycle.
Does MCP47CMB01-E/UN support external reference voltage with gain selection?
Yes, the MCP47CMB01-E/UN supports external reference voltage via the VREF pin with selectable 1x or 2x output gain. When 2x gain is enabled, the external VREF must not exceed VDD/2 to avoid clipping. The VREF pin accepts voltages from VSS to VDD and operates in buffered or unbuffered mode depending on register configuration. This functionality is fully supported in the MCP47CMB01-E/UN and does not require additional external components.
What is the settling time specification for MCP47CMB01-E/UN?
The MCP47CMB01-E/UN has a typical settling time of 16 µs to within ±0.5 LSb of final value for major code transitions (e.g., 1/4 to 3/4 of full scale). This specification is measured with RL = 2 kΩ and CL = 100 pF, and holds across the full operating temperature range (–40°C to +125°C). The MCP47CMB01-E/UN achieves this performance using its integrated rail-to-rail output amplifier with 60 kHz –3 dB bandwidth.
Can MCP47CMB01-E/UN operate over the extended temperature range?
Yes, the MCP47CMB01-E/UN is fully specified and tested for operation from –40°C to +125°C. All key parameters - including INL (±0.1 LSb), zero-scale error (≤0.375 LSb), and supply current - are guaranteed across this extended range. The device incorporates on-chip temperature compensation for its internal bandgap reference (1.214 V ±2.6%, ±16 ppm/°C), ensuring stable performance in automotive under-hood and industrial motor-control environments. This rating applies to the MCP47CMB01-E/UN in both MSOP and DFN packages.
