NXP Semiconductors MMA2204D

Overview

MMA2204D from Freescale Semiconductor is a surface-mount, silicon capacitive micromachined accelerometer with integrated signal conditioning, 4th-order Bessel low-pass filter, and factory-calibrated ±100g full-scale range along the X-axis. It delivers ratiometric linear output (20 mV/g typical sensitivity), operates from 4.75–5.25 V, draws 5.0 mA typical supply current, and supports –40°C to +125°C ambient operation - used in hard drive protection, appliance control, and vibration monitoring systems.

For engineers reviewing the MMA2204D datasheet, MMA2204D pinout, MMA2204D application, or MMA2204D equivalent, key selection considerations include its SOIC-16 package, self-test functionality, status fault latching, ESD-sensitive handling requirements, and ratiometric output compatibility with microcontroller ADCs.

Technical Context

The MMA2204D integrates a polysilicon g-cell transducer hermetically sealed at wafer level and a CMOS ASIC implementing switched-capacitor sensing, temperature compensation, and a 4-pole Bessel filter with fixed 360–440 Hz –3 dB bandwidth. Its analog output stage is ratiometric, with zero-g offset at VDD/2 and full-scale swing of ±100g mapped to ±1.0 V around midsupply under 5.0 V supply.

Self-test is initiated via logic-high ST pin, generating electrostatic deflection equivalent to ~12 g acceleration; STATUS pin latches high on Low Voltage Detect (trip at 2.7–4.0 V), clock monitor failure (<150 kHz or >400 kHz), or EPROM parity error, and resets only upon ST pulse if faults persist.

Equivalent & Alternatives

The following parts are listed as comparable options for similar accelerometer applications.

Compared with ADXL202E and MMA2202D, the MMA2204D uniquely combines ±100g range, integrated Bessel filter, STATUS fault latching, and calibrated self-test in a single-axis SOIC-16 package - making it optimal for ruggedized vibration monitoring and mechanical shock detection where diagnostic integrity is mandatory.

Availability

MMA2204D is available at Aetrix Electronics and suitable for hard drive protection, appliance control, and industrial vibration monitoring requiring stable component supply across extended temperature ranges and long production lifecycles.

Supply support for MMA2204D includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Freescale Semiconductor was a leading designer of embedded processors, analog, and sensor ICs, later acquired by NXP Semiconductors in 2015.

The MMA series was developed specifically for high-reliability industrial and automotive motion sensing, emphasizing hermetic packaging, built-in diagnostics, and factory-calibrated performance across wide temperature ranges.

FAQ

What is the full-scale acceleration range and axis orientation of the MMA2204D?

The MMA2204D has a ±100g full-scale range along the X-axis only. Its sensitivity is 20 mV/g typical, with zero-g output centered at VDD/2. Acceleration in the +X direction increases VOUT above midsupply; –X decreases it. The device is uniaxial and not sensitive to Y/Z axes beyond specified transverse sensitivity (≤10% FSO).

Does the MMA2204D require external components for basic operation?

Yes - the MMA2204D requires a 0.1 µF ceramic capacitor between VDD and VSS for power decoupling, and an RC filter (1 kΩ + 0.01 µF) on VOUT to suppress switched-capacitor clock noise. No external components are needed for filtering, calibration, or self-test activation, as those functions are fully integrated.

How does the STATUS pin function on the MMA2204D?

The STATUS pin on the MMA2204D is an open-drain output that latches high when any fault occurs: supply voltage drops below 2.7 V (LVD), internal clock frequency falls outside 150–400 kHz, or EPROM parity becomes odd. It remains high until a ≥100 µs ST pulse is applied - unless the underlying fault persists.

Is the MMA2204D RoHS-compliant and lead-free?

Yes - the MMA2204D is RoHS-compliant and Pb-free, as confirmed in the 2006 datasheet revision. Its "D" suffix denotes the standard leaded version, but Freescale explicitly states that RoHS-compliant variants retain identical functionality and electrical characteristics - with no derating or performance trade-offs.

Can the MMA2204D be used in automotive airbag systems?

No - the MMA2204D is not qualified for automotive safety-critical applications such as airbag deployment. Freescale explicitly disclaims use in systems supporting or sustaining life. While it includes self-test and fault detection, it lacks AEC-Q100 qualification, ASIL certification, and redundant architecture required for airbag controllers.
