# EMC3090 AT Module
#1. Introduction
- The EMC3090 series standard AT Combo module is an integrated hardware and firmware product launched by MXCHIP, used to quickly achieve product Wi Fi communication functions. It is equipped with standard AT firmware and achieves high-speed connectivity through a "development free" and "zero code" approach. It greatly shortens the development and launch cycles of customers' complete machine products.
- EMC3090-P is a Combo module of Wi Fi+BLE, with a working voltage of 3.3V and a working temperature of -20~85 ° C. It has a Cortex M33 core, a main frequency of up to 100MHz, 256K bytes of SRAM, 384K bytes of ROM, 2M bytes of XIP Flash, 2.4 GHz Wi Fi compliant with IEEE 802.11 b/g/n standard, low-power Bluetooth compliant with BLE4.2 specification, and supports Bluetooth networking.
