2. Product Specification

2.1. Chipset

7x7 mm

48 pin QFN IS1657NM

2.2. Interfaces

- Multi function GPIO interface

- Bluetooth RF interface

- HCI over URAT up to 921600 bps

- I2C for external EEPROM and authentication chip

- 2/4 wires SPI interface (master/slave) for external peripherals control. (Optional)

2.3. Hardware Design Considerations

- Power

The module requires either a 3.3V or 5V supply voltage. (3.3V was suggested)

- Power ramp-up timing restriction

1) BAT_IN : ramp-up (0 to 1.6V) < 200ms

2) PMULDO_O : PMU-logic ramp-up (0 to 1.6V) <60ms

3) VCC_RF (1.8V power domain) : RF BPOR ramp-up (0 to 1.6V) < 20ms

- Power on sequence

1) BAT_IN/ BAT_IN_5V: must be first!

2) 3.3V power domain: VDD_IO/ VDD_FIO must power-up early than 1.8V power.

3) 1.8V power domain: 1V8/ VCC_RF/ VDD_XO/ 1V8_U_P

4) RST_N: digital reset released from 0 to 1.6V must be the last one.
