Benefits |
| |
| |
| |
|
- Low-noise, low-leakage configurable sensor interface: ultra-low noise op-amps with low-leakage inputs, configurable outputs, and dual programmable gain amplifiers for optimal dynamic range scaling of sensor signals
|
|
- High precision sensing: The combination of dual 16-bit ADCs, a highly accurate voltage reference, triple 10-bit DACs and a 32-bit ARM Cortex-M3 processor enables the Q32M210 microcontroller to deliver high precision performance. The ultra-low-noise ADCs offer true 16-bit performance, unlike typical converters where nonlinearity and noise can reduce the number of effective bits.
|
- Flexible sensor interconnection scheme: 8:1 input multiplexing as well as four multi-switches and four SPST switches for effective connection to a wide range of sensors
|
|
- Predictable operation: Featuring on-chip power supervision with dedicated brownout protection circuitry and low battery detection, Q32M210 provides predictable operation under all battery conditions. Integrated error checking and correction circuitry monitors the on-chip flash memory, detecting and correcting single-bit errors and alerting when larger errors are detected.
|
- Efficient and powerful processing architecture: ARM Cortex-M3 processor-based mixed-signal data acquisition system, 256 kB on-chip flash for program and user data storage, 48 kB on-chip SRAM for storage of intermediate data during operation, and no external voltage required for flash write operation
|
|
- Highly integrated and optimized: All critical functions including a real-time clock, power management, oscillators and a full complement of peripherals are integrated within the Q32M210 microcontroller, reducing complexity, the need for external components and overall BOM cost.
|
- Ultra-low-power: less than 1 mA at 1 MHz core operation with basic sensor interface enabled, typical 3.0 V system supply voltage (2032 coin cell or similar), operation down to 1.8 V
Smart power management: including low current sleep mode (real-time clock active) consuming only 750 nA
|
|
- Extended battery life: Industry-leading power efficiency dramatically extends battery life. The ultra-low-power sensor interface, flexible clocking architecture, multiple operating modes (active, stand-by and sleep) and an intelligent power supply monitoring feature enable significantly reduced power consumption
|
- Low-noise A/D conversion: dual 16-bit, low power ADCs with on-the-fly data rate configurability
|
|
|
- Low-power D/A conversion: triple 10-bit DACs with configurable dynamic range
|
|
|
- Integrated Pulse Width Management (PWM): On-chip PWM capability combined with on-chip low on-resistance multi-switches eliminates the need for external driver MOSFETs
|
|
|
- Hardware ECC: built-in flash memory error checking and correction ensures greater reliability
|
|
|
- Flexible clocking architecture: supports speeds up to 16 MHz using either an internally or externally generated clock (USB interface operates at 48 MHz using a dedicated external crystal)
|
|
|
- Full range of configurable data interfaces: USB (2.0 full-speed compatible), PCM (including I2S mode), dual UARTs, dual SPI, SQI, I2C, GPIOs
|
|
|
- Flexible LCD interfacing: LCD (up to 112 segments) and integrated backlight driver via on-chip charge pump
|
|
|
- Smart power management: including low current sleep mode (real-time clock active) consuming only 750 nA
|
|
|
- Integrated precision voltage reference: <50ppm/C across the range 0C to 50C
|
|
|
- Integrated temperature measurement: designed accuracy is 0.8C
|
|
|
- Predictable operation: dedicated brown-out protection circuitry and a watchdog to help maintain predictable operation
|
|
|
|
