N572F065
Description
The N572F065 is the first Cortex™-M0 based processor for voice process applications, running up to 48MHz and equipped with 64KB flash and 8KB SRAM for high performance process of audio and voice algorithms. Integrating rich analog peripherals, like pre-amplifier, ADC, DAC, hardware mixer, and PA, this chip saves a lot of system design effort and cost.
Key Features
- Core - ARM® Cortex™-M0 core runs up to 48MHz. - Support low power sleep mode - Single-cycle 32-bit hardware multiplier. - NVIC for the 16 interrupt inputs, each with 4-levels of priority. - Serial Wire Debug supports with 2 watchpoints/4 breakpoints.
- Widely operating voltage range from 2.4V to 5.5V
- Flash EPROM Memory - 64K bytes Flash EPROM - Support ISP for Flash update - 512 bytes page erase for Flash - Support 2-wire ICP update from ICE interface - Support fast parallel programming mode by external programmer.
- SRAM Memory - 8K bytes embedded SRAM.
- Clock Control - Flexible selection for different applications. - Support PLL, up to 48MHz, for high performance system operation. - External 12MHz (or 6MHz) crystal input for USB and precise timing operating mode. - External 32KHz crystal input for RTC function and system clock. - Internal 24MHz RC oscillator.
- GPIO - Four I/O modes:; Quasi bi-direction; Push-Pull output; Open-Drain output; Input only with high impendence - TTL/Schmitt trigger input selectable. - I/O pin can be configured as interrupt source with edge/level setting. - High driver and high sink IO mode support.
- Timers - 3 sets of the timer with 8-bit pre-scalar and 16-bit timer. - Counter auto reload. - IR carrier generator - One fixed frequency timer
- Watch Dog Timer - Default ON/OFF by configuration setting - Multiple clock sources - 8 selectable time out period from 6ms ~ 3.0sec (depends on clock source) - WDT can wake up power down/sleep. - Interrupt or reset selectable on watchdog time-out.
- RTC - Support time out interrupt - Support wake up function.
- PWM/Capture/Compare Timer - one 16-bit timers and four 16-bit comparators August 16, 2014 Page 7 of 206 Rev. 1.00
