Analog Devices Inc. ADuCM36x ARM Cortex-M3-MCUs
Analog Devices ADuCM36x Mikrocontroller (MCUs) bieten ein vollständig integriertes 3,9 kSPS-24-Bit-Datenerfassungssystem. Diese Mikrocontroller vereinen eine hohe Leistungsfähigkeit, Sigma-Delta-(Σ-Δ)-Analog-Digital-Wandler (ADCs) und einen 32-Bit ARM Cortex™-M3-Prozessor. Außerdem enthalten die ADuCM36x einen 32-kHz-On-Chip-Oszillator und einen integrierten 16-MHz-Hochfrequenz-Oszillator. Der ADuCM36x integriert On-Chip-Peripheriegeräte wie UART, I²C und serielle Dual-SPI-I/O-Kommunikations-Controller. Zusätzliche Peripheriegeräte umfassen eine 16-Bit-PWM mit 6 Ausgangskanälen, 19-Pin-GPIO-Ports, 2 Allzweck-Timer, Wake-up-Timer und System-Watchdog-Timer. Entwickler können den Mikrocontroller in einem normalen Betriebsmodus, der einen Stromverbrauch von 290μA/MHz (einschließlich Flash/SRAM IDD) bietet, konfigurieren. Der normale Betriebsmodus bietet einen Stromverbrauch von insgesamt 1 mA, wenn alle Peripheriegeräte aktiv sind. Durch ihren geringen Stromverbrauch eignen sich die ADuCM36x MCUs ideal für den Betrieb von batteriebetriebenen Applikationen, bei denen ein Betrieb mit geringem Stromverbrauch unerlässlich ist.Designers can configure the microcontroller in a normal operating mode that consumes 290μA/MHz (including flash/SRAM IDD). The normal operating mode results in an overall system current consumption of 1mA when all peripherals are active. With its low-power operation, the ADuCM36x MCUs are ideally suited to operate in battery-powered applications where low-power operation is critical.
