1 Product Overview

1.1 Brief Introduction

E70-900M14S1B adopts the original imported CC1312R from Texas

Instruments (TI). It integrates a single-chip microcomputer and wireless transceiver,
and uses a 48MHz industrial-grade high-precision low-temperature drift crystal
oscillator to ensure its industrial characteristics and stable performance.

The CC1312R chip has a built-in powerful 48MHz Arm Cortex-M4F

processor, and has abundant peripheral resources such as UART, I2C, SPI, ADC,
DMA, and PWM. The module leads to all the IO ports of the single-chip
microcomputer, which can be used for multi-directional development.

Since the E70-900M14S1B is a pure hardware SOC module, there is no program at the factory, and the user needs to develop it

again before it can be used.

1.2 Feature

Developed based on CC1312R, built-in powerful 48MHz Arm Cortex-M4F processor;

With 48MHz temperature compensated crystal oscillator, industrial-grade standard design

352KB system programmable flash memory, 256KB ROM for protocol and library functions

8KB cache SRAM (available as general-purpose RAM), 80KB ultra-low leakage SRAM, SRAM adopts parity check protection
to ensure high reliability of operation

RSSI signal strength reading

Air wake-up, that is, low power consumption function, suitable for battery-powered solutions

Ultra-low receiving current, its receiving current is only half of similar products

The maximum transmit power is 25mW, and the software is multi-level adjustable

For European license-free frequency band ISM 868MHz and North America license-free ISM 915MHz frequency band

Air transmission rate: 20

1000kbps

2.2

3.8V power supply, power supply greater than or equal to 3.3V can guarantee the best performance

Under ideal conditions, the communication distance can reach 1.5km

Dual antennas are optional (IPEX/stamp hole), which is convenient for users to develop and integrate.
