ISD9160 Datasheet
2 FEATURES
• Core
– ARM® Cortex™-M0 core runs up to 50MHz.
– One 24-bit System tick timer for operating system support.
– Supports a variety of low power sleep and power down modes.
– Single-cycle 32-bit hardware multiplier.
– NVIC (Nested Vector Interrupt Controller) for 32 interrupt inputs, each with 4-levels of priority.
– Serial Wire Debug (SWD) support with 2 watchpoints/4 breakpoints.
• Power Management
– Wide operating voltage range from 2.5V to 5.5V.
– Power management Unit (PMU) providing four levels of power control.
– Deep Power Down (DPD) mode with sub micro-amp leakage (<1µA).
– Wakeup from Deep Power Down via dedicated WAKEUP pin or timed operation from internal
low power 10kHz oscillator.
– Standby mode with limited RAM retention and RTC operation (<10µA).
– Wakeup from Standby can be from any GPIO interrupt, RTC or BOD.
– Sleep mode with minimal dynamic power consumption.
– 3V LDO for operation of external 3V devices such as serial flash.
• Flash EPROM Memory
– 145K bytes Flash EPROM for program code and data storage.
– 4KB of flash can be configured as boot sector for ISP loader.
– Support In-system program (ISP) and In-circuit program (ICP) application code update
– 1K byte page erase for flash
– Configurable boundary to delineate code and data flash.
– Support 2 wire In-circuit Programming (ICP) update from SWD ICE interface
• SRAM Memory
– 12K bytes embedded SRAM.
• Clock Control
– One high speed and two low speed oscillators providing flexible selection for different
applications. No external components necessary.
– Built-in trimmable oscillator with range of 16-50MHz. Factory trimmed within 1% to settings of
49.152MHz and 32.768MHz. User trimmable with in-built frequency measurement block
(OSCFM) using reference clock of 32kHz crystal or external reference source.
– Ultra-low power (<1uA) 10kHz oscillator for watchdog and wakeup from power-down or sleep
operation.
– External 32kHz crystal input for RTC function and low power system operation.
• 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.
– Switchable pull-up.
• Audio Analog to Digital converter
– Sigma Delta ADC with configurable decimation filter and 16 bit output.
– 80dB Signal-to-Noise (SNR) performance.
– Programmable gain amplifier with 32 steps from -12 to 35.25dB in 0.75dB steps.
– Boost gain stage of 26dB, giving maximum total gain of 61dB.
