Introduction
The HR_C6000 chip independently developed by Hongrui complies with the ETSI TS102 361
(DMR) digital intercom standard, while supporting digital PDT cluster intercom, analog intercom
and analog cluster intercom application is a terminal chip for high-end applications.
The chip integrates a high-performance 4FSK modem, MSK modem, analog intercom channel, sub-
audio, DTMF, 2-Tone, 5-Tone and other analog functions, channel coding code, protocol processor,
physical layer, data link layer and call control layered design, users can directly use the three-layer
protocol to develop DMR-compliant digital walkie-talkies, greatly reduced the development
workload and shorten the development time; users can also perform PDT based on the HR_C6000
Layer 2 protocol.
Development of protocols, DMR TierIII or custom protocols to meet the needs of high-end users.
The chip is suitable for digital intercoms, dedicated cluster terminals, as well as low-speed data and
voice transmission terminal applications, support relay and terminal applications in a centralized
mode.
The chip has built-in AD/DA, CodeC, DC-DC and other IP to effectively reduce the user's
peripheral devices. At the same time, it can sewing and docking AMBE3000, WT3000,
AMBE1000, HR_V3000, SELP, AVDS and other vocoders, two-point modulation transmission, low
IF reception, compatible with the original analog walkie-talkie RF channel, reducing the workload
of user RF development.
The chip is powered by 3.3V and has a built-in power management module for low power design.
The product is available in the LQFP-80 package.
