- Vibration motor driver programmable from 1.2 to 3.1 V in 100 mV increments
- Two-channel speaker driver with programmable gain, turn-on time, and muting; configurable inputs and
outputs capable of stereo or mono operation (drives external 8-Ω speakers with volume controlled 500
mW, each channel)
- Video (TV) amplifier allows use as a camcorder or for slide presentations
• IC-level interfaces
- Configurable SBI (three-wire or single-wire) for efficient initialization, status, and control
- Supports MSM interrupt processing with an internal interrupt manager
- Many functions monitored and reported through real-time and interrupt status signals
- Dedicated circuits for controlled poweron sequencing, including the MSM device's reset signal
- Several events continuously monitored for triggering poweron/poweroff sequences
- Supports and orchestrates soft resets
- USB-OTG transceiver for full-speed (12 Mb/s) and low-speed (1.5 Mb/s) interfacing of the MSM device to
computers as a USB peripheral, or connecting the MSM device to other peripherals
- Two sets of RUIM level translators enable MSM device interfacing with external modules
• 22 multipurpose pins that can be configured as digital or analog I/Os, bidirectional I/Os, or current sinks;
default functions support the two sets of RUIM level translators, poweron circuits, analog multiplexer
inputs, an LED driver, and a selectable reference voltage output.
• Highly integrated functionality in a small package - 137-pin CSP with a several center ground pins for
electrical ground, mechanical stability, and thermal relief
