The MAX32675C is a highly integrated, mixed-signal, ultra-low-power microcontroller for industrial applications and is especially suitable for 4-20mA loop-powered sensors and transmitters. It is based on an ultra-low-power Arm® Cortex®- M4 with floating point unit (FPU) and includes 384KB (376KB user) flash and 160KB of SRAM. Error correction coding (ECC), capable of single-error correction, double-error detection (SEC-DED), is implemented over the entire flash, SRAM, and cache to ensure ultra-reliable code execution for demanding applications.
An analog front-end (AFE) with an integrated, low-power HART modem enables the bidirectional transfer of digital data over a current loop with industrial sensors for configuration and diagnostics. The AFE also provides two 12-channel delta-sigma (Δ-Σ) ADCs with features and specifications optimized for precision sensor measurement. Each Δ-Σ ADC can digitize external analog signals as well as system temperature. A PGA with gains of 1x to128x precedes each ADC. ADC outputs can be optionally converted on the fly from integer to single-precision floating-point format. A 12-bit DAC is also included.
The device also provides robust security features, including an AES engine and persistent key storage.
APPLICATIONS
- 4-20mA Industrial Sensors and Transmitters
- Industrial Pressure, Temperature, Flow, and LevelSensors/Transmitters
- Medical Pressure, Temperature, and Flow Sensors
