ISD9300 Datasheet, PDF (6/26 Pages) List of Unclassifed Manufacturers – ISD Cortex-M0 ChipCorder

ISD9300 Datasheet
 I2C
– Master/Slave up to 1Mbit/s
– Bidirectional data transfer between masters and slaves
– Multi-master bus (no central master).
– Arbitration between simultaneously transmitting masters without corruption of serial data on
the bus
– Serial clock synchronization allows devices with different bit rates to communicate via one
serial bus.
– Serial clock synchronization can be used as a handshake mechanism to suspend and resume
serial transfer.
– Programmable clock allowing versatile rate control.
– I2C-bus controller supports multiple address recognition.
 I²S
– Interface with external audio CODEC
– Operate as either master or slave
– Capable of handling 8, 16, 24 and 32 bit word sizes
– Mono and stereo audio data supported
– I²S and MSB justified data format supported
– Two 8 word FIFO data buffers are provided, one for transmit and one for receive
– Generates interrupt requests when buffer levels cross a programmable boundary
– Supports DMA requests, for transmit and receive
 Brown-out detector
– With 16 levels: 2.3V, 2,4V, 2.6V, 2.7V, 2.8V, 3.0V, 3.2V, 3.3V, 3.4V, 3.6V, 3.8V, 3.9V, 4.0V, 4.1V,
4.4V, 4.8V.
– Supports time-multiplex operation to minimize power consumption
– Supports Brownout Interrupt and Reset option
 Built in Low Dropout Voltage Regulator (LDO)
– Capable of delivering 30mA load current.
– Configurable for output voltage of 1.8V, 2.4V, 3.0V and 3.3V
– Eight GPIO (GPIOA<7:0>) operate from LDO voltage domain allowing direct interface to, for
example, 3V SPI Flash.
– Can be bypassed and voltage domain supplied directly from system power.
 Additional Features
– Over temperature alarm. Can generate interrupt if device exceeds safe operating temperature.
– Temperature proportional voltage source which can be routed to ADC for temperature
measurements.
– Digital Microphone interface.
 Operating Temperature: -40C~85C
 Package:
– All Green package (RoHS)
 LQFP 64-pin
