Product details
Overview
MC13234CHTR from Freescale Semiconductor is a 2.4 GHz IEEE 802.15.4/ZigBee RF4CE-compliant system-on-chip integrating an HCS08QE 8-bit MCU, 128 KB flash, 8 KB SRAM, and a fully integrated transceiver with -94 dBm receive sensitivity, +2 dBm max TX power, and 250 kb/s data rate - deployed in TV, Blu-ray, and set-top box remote controls.
For engineers reviewing the MC13234CHTR datasheet, MC13234CHTR pinout, MC13234CHTR application, or MC13234CHTR equivalent, this SoC delivers verified RF4CE protocol stack support, low-power RX/PPD modes (22 mA / 450 nA), 32 MHz CPU clock, 48-LGA package, and hardware AES-128/CCM acceleration for secure consumer remote control design.
Technical Context
The MC13234CHTR implements a dedicated IEEE 802.15.4 PHY/MAC accelerator with DMA interface and hardware AES-128/CCM encryption, enabling ZigBee RF4CE stack execution without external co-processor. Its HCS08QE core runs at up to 32 MHz CPU frequency with 16 MHz bus speed and supports seven addressing modes plus fast 8×8 multiply and 16÷8 divide instructions.
RF subsystem includes integrated TX/RX switch, balun, 2.4 GHz PLL, and programmable output power (-30 to +2 dBm). System-level timing uses a 32 MHz reference oscillator with programmable capacitive loading and optional 32.768 kHz crystal for low-power wake-up timer operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2.4 GHz RF4CE remote control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC13237CHTR2 | Includes 12-bit ADC; otherwise identical flash/RAM, RF, and peripheral set | Required when remote integrates analog sensors (e.g., ambient light, temperature) alongside RF control | Select MC13237CHTR2 only if ADC functionality is needed; MC13234CHTR remains optimal for pure RF4CE remotes |
| EM3581-RTR | ARM Cortex-M3 core; higher memory (256 KB flash/32 KB RAM); ZigBee Pro stack support | Targets complex mesh networks and gateway-class devices, not optimized for ultra-low-cost remotes | Choose EM3581-RTR for scalable ZigBee HA deployments; MC13234CHTR better fits cost-sensitive, single-purpose remote designs |
Compared with MC13237CHTR2, MC13234CHTR saves BOM cost by omitting unused ADC circuitry; versus EM3581-RTR, it delivers lower power consumption (450 nA sleep) and simpler toolchain integration for RF4CE-only use cases.

FAQ
What wireless standard does the MC13234CHTR implement?
The MC13234CHTR implements the IEEE 802.15.4-2006 physical and MAC layers, enabling full ZigBee RF4CE protocol stack operation. It supports 16 channels in the 2.4 GHz ISM band, 250 kb/s data rate, and hardware-accelerated AES-128/CCM encryption - all required for certified remote control interoperability. The MC13234CHTR does not support Bluetooth, Wi-Fi, or proprietary 315/433 MHz protocols.
Does the MC13234CHTR include an analog-to-digital converter (ADC)?
No, the MC13234CHTR does not include an ADC. That feature is exclusive to the MC13237 variant (e.g., MC13237CHTR2), which integrates a 12-bit ADC for sensor interfacing. The MC13234CHTR is optimized for pure RF4CE remote control applications where analog sensing is unnecessary, reducing die size and cost.
What is the operating voltage range and power consumption profile of the MC13234CHTR?
The MC13234CHTR operates from 1.8 V to 3.6 V with on-chip voltage regulation and low-battery detection. In active RX mode, it draws 34 mA; in TX mode at 0 dBm, 27 mA; in low-power PPD RX mode, 22 mA; and in deep sleep, as low as 450 nA. This enables multi-year battery life in alkaline-powered remote controls.
Is the MC13234CHTR pin-compatible with other members of the MC1323x family?
Yes, the MC13234CHTR is pin-compatible with MC13237CHT and MC13237CHTR2 in the same 48-LGA package. Both share identical pinout, power domains, and peripheral mapping. The only functional difference is the absence of the 12-bit ADC in MC13234CHTR - all GPIO, UART, SPI, KBI, and RF interfaces remain electrically and logically identical.
What development tools and software support are available for the MC13234CHTR?
Freescale's BeeKit Wireless Toolkit provides GUI-based configuration for MC13234CHTR network parameters, supporting SMAC, IEEE 802.15.4 MAC, SynkroRF, and BeeStack Consumer (ZigBee RF4CE) stacks. Reference designs, schematics, Gerbers, and pre-programmed development boards are available - enabling functional RF4CE remote prototypes within 15 minutes of setup.
