MC3630 3-Axis Accelerometer
Preliminary Datasheet
GENERAL DESCRIPTION
FEATURES
The MC3630 is an ultra-low power, low-
noise, integrated digital output 3-axis
accelerometer with a feature set optimized
for wearables and consumer product
motion sensing. Applications include
wearable consumer products, IoT devices,
user interface control, gaming motion input,
electronic compass tilt compensation for
cell phones, game controllers, remote
controls and portable media products.
Low noise and low power are inherent in
the monolithic fabrication approach, where
the MEMS accelerometer is integrated in a
single-chip with the electronics integrated
circuit.
Range, Sampling & Power
 ±2, 4, 8, 12 or 16g ranges
 8, 10 or 12-bit resolution with FIFO
o 14-bit single samples
 Sample rate 14 - 1300 samples/sec
o Sample trigger via internal oscillator,
clock pin or software command
 Sniff and Wake modes
o 0.4 μA Sniff current @ 6Hz
o Separate or combined sniff/wake
 Ultra-Low Power with 32 sample FIFO
o 0.9 μA typical current @ 25Hz
o 1.6 μA typical current @ 50Hz
o 2.8 μA typical current @ 100Hz
o 36 μA typical current @ 1300Hz
In the MC3630 the internal sample rate can
be set from 14 to 1300 samples / second.
Specific tap or sample acquisition
conditions can trigger an interrupt to a
remote MCU. Alternatively, the device
supports the reading of sample and event
status via polling.
Simple System Integration
 I2C interface, up to 1 MHz
 SPI Interface, up to 4 MHz
 2.0 × 2.0 × 0.94 mm 12-pin package
 Single-chip 3D silicon MEMS
 Low noise to 2.3mgRMS
