Description


The CMT2189D is a low-power SoC RF transmitter embedded with enhanced 1T-8051 core:

  1. The series chips support 27 - 960 MHz, OOK or (G)FSK modulation wireless transmission function.

  2. The high-efficient single-ended PA supports adjustable output power ranging in 0 ~ +13 dBm, with +13 dBm transmission consuming merely a power of 18 mA.

  3. It supports 8 kB OTP program storage and 12 kB ROM (for storage of API function library).

  4. 1-WIRE online simulation function is adopted. Users can download target debugging code directly to on-chip PRAM to run, through the dedicated 1-WIRE debugger, which can achieve quite convenient debugging rather than traditional OTP chip debugging that requires specific simulator with no support of online simulation and results in quite troublesome operations.

  5. The support of embedded AES-128 accelerator and truly random number generator (TRNG) as well as 32-bit sequence number (ID) makes it suitable for transmission application scenarios with enciphering requirements, such as remote control and active RFID.

  6. It supports dual-clock architecture, with the internal high-speed clock supporting system internal running, and the internal low-power RC oscillator supporting low-power timer based wake-up mode operating.

  7. The embedded 12-bit high-precision and high-speed SAR-ADC is fitting for sensors used in wireless acquisition application scenarios.
