Product details
Overview
MCP47CMB01-E/MG from Microchip Technology is a single-channel, 8-bit nonvolatile memory digital-to-analog converter (DAC) with I²C interface, ±0.1 LSb integral nonlinearity, 1.214 V internal bandgap reference, and operation from 2.7V to 5.5V. It delivers buffered voltage output for precision trimming in sensor calibration and portable instrumentation.
For engineers reviewing the MCP47CMB01-E/MG datasheet, MCP47CMB01-E/MG pinout, MCP47CMB01-E/MG application, or MCP47CMB01-E/MG equivalent, key selection criteria include nonvolatile MTP programming (32 cycles), dual power-down resistor options (1 kΩ/100 kΩ), I²C high-speed mode support (up to 3.4 Mbps), and extended temperature range (-40°C to +125°C).
Technical Context
The MCP47CMB01-E/MG implements a resistor ladder architecture with buffered op-amp output and selectable reference sources (VDD, external VREF, or internal 1.214 V bandgap). Its nonvolatile memory stores power-up DAC values, configuration registers, and general-purpose data across 8 MTP locations.
I²C communication supports Standard (100 kHz), Fast (400 kHz), and High-Speed (1.7 MHz / 3.4 MHz) modes with register-defined slave addressing via A0/A1 pins. Power-on/brown-out reset ensures deterministic startup, and LAT/HVC pin enables high-voltage MTP programming at 7.5 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP47CVB01-E/MG | Volatile RAM only (no MTP); identical pinout, resolution, and I²C interface | Requires host MCU to reload DAC value after each power cycle | Select when factory calibration is performed at final assembly and no field recalibration is needed |
| DAC8560IDGKT | 16-bit resolution, SPI interface, no internal reference, higher supply current (600 µA) | Higher precision but incompatible protocol and footprint; requires external reference and level-shifting | Choose only if 16-bit resolution and SPI are mandatory; not drop-in compatible |
Compared with MCP47CVB01-E/MG, the MCP47CMB01-E/MG adds nonvolatile configuration retention at no cost to speed or power; versus DAC8560IDGKT, it trades resolution and interface flexibility for guaranteed pin compatibility, lower power, and integrated reference - making it optimal for cost-sensitive, space-constrained recalibration tasks.

FAQ
What is the maximum I²C clock frequency supported by the MCP47CMB01-E/MG?
The MCP47CMB01-E/MG supports I²C Standard Mode (100 kHz), Fast Mode (400 kHz), and High-Speed Mode up to 3.4 Mbps. High-Speed Mode requires compliant I²C master hardware and proper signal integrity layout - slew rate limiting and termination may be necessary above 1 Mbps. All modes retain full register access and MTP programming functionality.
Does the MCP47CMB01-E/MG require an external high-voltage supply for MTP programming?
Yes - the LAT/HVC pin must be driven to 7.5 V (±0.25 V) to initiate MTP write operations on the MCP47CMB01-E/MG. This voltage is applied externally during programming; no internal charge pump is present. The 7.5 V level is only required during the 250 µs write cycle - it must be removed immediately afterward to avoid damage.
Can the MCP47CMB01-E/MG operate from a 1.8 V supply?
The MCP47CMB01-E/MG supports 1.8 V to 2.7 V VDD operation for I²C interface functionality, but analog specifications (INL, gain error, settling time) are degraded per datasheet. Full electrical performance - including ±0.1 LSb INL and 16 µs settling - is guaranteed only from 2.7 V to 5.5 V. Use 2.7 V minimum for precision applications.
How many times can the nonvolatile memory of the MCP47CMB01-E/MG be rewritten?
The MCP47CMB01-E/MG provides 32 guaranteed write cycles per MTP memory location. After the 32nd write, further attempts are ignored and the last written value persists. This endurance is sufficient for factory calibration and occasional field updates but not for runtime parameter logging.
What is the purpose of the WiperLock™ feature in the MCP47CMB01-E/MG?
WiperLock™ prevents unintended DAC code changes due to I²C bus noise or spurious start/stop conditions on the MCP47CMB01-E/MG. It locks the DAC output register until a valid command sequence is received, ensuring output stability in electrically noisy environments such as motor drives or industrial PLCs.
