ISD9300 Datasheet
2 FEATURES
ï· Core
â ARM® Cortexâ¢-M0 core runs up to 98.304MHz.
â One 24-bit System tick timer for operating system support.
â Supports a variety of low power sleep and power down modes.
â Single-cycle 32-bit hardware multiplier.
â NVIC (Nested Vector Interrupt Controller) for 32 interrupt inputs, each with 4-levels of priority.
â Serial Wire Debug (SWD) support with 2 watchpoints/4 breakpoints.
ï· Power Management
â Wide operating voltage range from 2.4V to 5.5V.
â Power management Unit (PMU) providing four levels of power control.
â Deep Power Down (DPD) mode with sub micro-amp leakage (<1µA).
â Wakeup from Deep Power Down via dedicated WAKEUP pin or timed operation from internal
low power 16KHz oscillator.
â Standby mode with limited RAM retention and RTC operation (<10µA).
â Wakeup from Standby can be from any GPIO interrupt, RTC or BOD.
â Sleep mode with minimal dynamic power consumption.
â 3V LDO for operation of external 3V devices such as serial flash.
ï· Flash EPROM Memory
â 68/100/145K bytes Flash EPROM for program code and data storage.
â Pre-fetch and mini-cache for near zero-wait state memory access.
â 4KB of flash can be configured as boot sector for ISP loader.
â Support In-system program (ISP) and In-circuit program (ICP) application code update
â 1K byte page erase for flash
â Configurable boundary to delineate code and data flash.
â Support 2 wire In-circuit Programming (ICP) update from SWD ICE interface
â Pre-fetch and cache for near zero-wait state memory operation.
ï· SRAM Memory
â 16K bytes embedded SRAM.
ï· Clock Control
â One high speed and two low speed oscillators providing flexible selection for different
applications. No external components necessary.
â Built-in trimmable oscillator with range of 16-50MHz. Factory trimmed within 1% to settings of
98.304MHz. User trimmable with in-built frequency measurement block (OSCFM) using
reference clock of 32kHz crystal or external reference source.
â Ultra-low power (<1uA) 16kHz oscillator for watchdog and wakeup from power-down or sleep
operation.
â External 32kHz crystal input for RTC function and low power system operation.
ï· GPIO
â Four I/O modes:
ïµ Quasi bi-direction
ïµ Push-Pull output
ïµ Open-Drain output
ïµ Input only with high impendence
â TTL/Schmitt trigger input selectable.
â I/O pin can be configured as interrupt source with edge/level setting.
â Switchable pull-up.
ï· Audio Analog to Digital converter
â Sigma Delta ADC with configurable decimation filter and 16 bit output.
â 90dB Signal-to-Noise (SNR) performance.
