Product details
Overview
MCP47CMD02-E/UN from Microchip Technology is a dual-channel, 8-bit nonvolatile voltage-output DAC with I²C interface, ±0.1 LSb integral nonlinearity, 2.7V–5.5V supply range, and internal 1.214V bandgap reference - used for precision sensor calibration and set-point trimming in industrial control modules.
For engineers reviewing the MCP47CMD02-E/UN datasheet, MCP47CMD02-E/UN pinout, MCP47CMD02-E/UN application, or MCP47CMD02-E/UN equivalent, this page delivers verified electrical specs, package mapping to 10-lead MSOP, dual-channel power-down behavior, MTP memory write cycle limits, and real-world timing performance including 4 µs settling time and 3.4 Mbps I²C support.
Technical Context
The MCP47CMD02-E/UN integrates two independent 8-bit resistor-ladder DACs with buffered voltage outputs, each selectable between VDD, external VREF (buffered/unbuffered), or internal 1.214V bandgap reference. Its MTP memory stores power-up output values, configuration registers, and general-purpose data across 32 write cycles per location.
It supports Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) I²C modes with register-defined addressing via A0/A1 pins. The LAT/HVC pin enables high-voltage programming (7.5V typical) for nonvolatile writes, while POR/BOR ensures reliable initialization across -40°C to +125°C operation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP47FVB02-E/MS | Volatile memory only; no MTP; identical pinout and resolution | Requires host MCU to reload DAC values after every power cycle | Choose when calibration data is stored externally and reloaded dynamically |
| AD5662BRMZ-2REEL7 | 16-bit resolution; SPI interface; no internal reference; different pinout (10-lead MSOP but incompatible mapping) | Higher precision needed; existing SPI infrastructure; no nonvolatile storage requirement | Choose when resolution > 8-bit is mandatory and I²C is not required |
Compared with MCP47FVB02-E/MS, the MCP47CMD02-E/UN adds nonvolatile configuration retention without layout change; compared with AD5662BRMZ-2REEL7, it trades resolution for I²C compatibility, integrated reference, and guaranteed MTP endurance - making it optimal for cost-sensitive, calibration-critical embedded systems.

FAQ
What is the maximum I²C clock frequency supported by the MCP47CMD02-E/UN?
The MCP47CMD02-E/UN supports High-Speed I²C mode up to 3.4 Mbps, in addition to Standard (100 kHz) and Fast (400 kHz) modes. This allows rapid configuration of both DAC channels in time-critical applications. The SCL and SDA pins feature Schmitt-trigger inputs and 10 pF pin capacitance, ensuring robust timing margins even with bus capacitance up to 400 pF.
Does the MCP47CMD02-E/UN require an external reference voltage?
No - the MCP47CMD02-E/UN includes an internal 1.214V bandgap reference (±2.5% initial tolerance, ±18 ppm/°C tempco) that can be selected as the DAC reference source. It also supports VDD or an external VREF (1.0V to VDD) with optional 1x or 2x gain, giving designers flexibility in accuracy, power, and headroom trade-offs without adding external components.
How many times can the nonvolatile memory of the MCP47CMD02-E/UN be programmed?
The MCP47CMD02-E/UN's MTP memory supports up to 32 write cycles per memory location. Each write requires a 7.5V pulse on the LAT/HVC pin and takes ≤250 µs. After 32 cycles, further writes are inhibited and the last valid value is retained - a design safeguard ensuring field calibration integrity over product lifetime.
What is the settling time specification for the MCP47CMD02-E/UN, and under what conditions is it measured?
The MCP47CMD02-E/UN achieves 4 µs settling time to within ±0.5 LSb of final value, measured when transitioning between 1/4 and 3/4 of full-scale (e.g., 40h to C0h for 8-bit). This is specified with RL = 2 kΩ and CL = 100 pF, and applies to both VOUT0 and VOUT1 independently - enabling fast update rates in real-time control loops.
Can the two DAC outputs of the MCP47CMD02-E/UN be powered down independently?
Yes - the MCP47CMD02-E/UN supports independent power-down control for VOUT0 and VOUT1 via dedicated PD0 and PD1 bits in the configuration register. Each output can be placed in high-impedance state with optional 100 kΩ or 1 kΩ pull-down to VSS, allowing selective channel shutdown without affecting the other DAC's operation or stored configuration.
