ITM-1066A User Manual 1. General Description iTM-1066A module features a fully integrated 2.4GHz+5GHz radio transceiver and baseband processor for Wi-Fi 802.11a/b/g/n IOT applications. It can be used as a standalone application-specific communication processor or as a wireless data link in hosted MCU systems. iTM-1066A module uses a highly integrated dual-band WIFI IOT SoC chipset equipped with a powerful and cost-competitive RISC processor, Andes Technology N10. It can be connected to any external MCU through UART, SPI, SDIO, USB or I2C interfaces and sensors or other devices through GPIOs. It also includes RF switch, balun, power amplifier (PA) and low noise amplifier (LNA), to minimize PCB design area and external component requirement.

ITM-1066A User Manual 6. Hardware Design Guidelines 6-1 Reference Design GPIO3 and GPIO13 must be HIGH when power-on. GPIO20 MUST be LOW when power-on (A 100K-ohm pull-low resistor is recommended) J3A and J4A are for firmware upgrade through USB interface Pulling up GPIO14/15 when power-on will force the module enter USB mode for firmware upgrade. However, J3A and J4A must be as close to GPIO14/15 pins as possible. Otherwise, the PCB traces of GPIO14/15 may cause EMI problem, because GPIO14 and GPIO15 are SPI flash clock/data pins when the module is in normal operation mode.
