The ATSAM4LC2AA from Microchip is a low-power ARM Cortex-M4 MCU running at 48MHz. It features 128KB flash, 32KB RAM, and an integrated LCD controller, making it ideal for metering and portable devices. Operating from 1.68V to 3.6V, it includes DMA, I2S, PWM, and WDT in a 48-VFQFN package.
- Integrated LCD controller: Eliminates external display driver ICs, saving cost and PCB space.
- Ultra-low voltage operation (1.68V): Extends battery life in single-cell applications.
- Cortex-M4 with DSP: Efficiently handles signal processing for audio and sensor data.
- Rich peripheral set (DMA, I2S, PWM): Enables complex system integration without external components.
Smart Meters (Water/Gas)
Integrated LCD controller drives segment displays directly, reducing BOM cost; low voltage (1.68V) supports battery operation.
Portable Instrumentation
Cortex-M4 with DSP instructions accelerates FFT for spectrum analyzers; 32KB RAM buffers samples.
Medical Wearables
48MHz core with I2S interfaces to audio codecs for hearing aids; low power extends usage time.
Industrial HMIs
LCD controller and PWM backlight control create simple user interfaces for machine controls.
Building Automation Thermostats
DMA and I2S handle sensor fusion (temp, humidity, motion) while LCD shows status; WDT ensures reliability.
RFID Readers
High-speed Cortex-M4 processes tag data quickly; low power modes preserve battery in handheld units.
