Product details
Overview
MC13233CR2 from Freescale Semiconductor is a fully integrated IEEE 802.15.4-compliant System-on-Chip (SoC) combining a 2.4 GHz O-QPSK transceiver, HCS08 8-bit CPU, 82 KB FLASH, 5 KB RAM, and hardware AES-128 security in a 7×7 mm LGA-48 package. It delivers -94 dBm receive sensitivity at 1% PER, 0 dBm nominal TX output power, and supports RF4CE remote control applications for consumer electronics.
For engineers reviewing the MC13233CR2 datasheet, MC13233CR2 pinout, MC13233CR2 application, or MC13233CR2 equivalent, this page provides verified technical context, real-world use scenarios, validated alternatives, and supply-chain-ready availability details - all grounded in Freescale's MC1323x Advance Information Rev. 1.0 documentation.
Technical Context
The MC13233CR2 integrates an IEEE 802.15.4-2006 PHY/MAC accelerator with hardware DMA, 802.15.4 auto-sequence support, and receiver frame filtering - offloading protocol stack execution from the HCS08 core. Its transceiver uses a differential RF port with integrated T/R switch and balun interface, operating across 16 channels in the 2.4 GHz ISM band at 250 kbps.
Power management includes Partial Power Down (PPD_RX) "listen" mode reducing RX current while maintaining programmable energy-detection thresholds, plus STOP3 mode drawing <1 μA. Clocking relies on a 32 MHz crystal oscillator with onboard load trim and optional 32.768 kHz RTC crystal support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar IEEE 802.15.4 SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI CC2530F256 | 8051 core, 256 KB FLASH, integrated 2.4 GHz RF front-end but no balun interface; requires external matching network. | Supports ZigBee PRO and Smart Energy profiles; broader stack maturity but larger memory footprint. | Choose CC2530F256 when migrating to ZigBee-certified mesh networks requiring larger application code space. |
| NXP JN5169 | ARM Cortex-M0+, 512 KB FLASH, integrated 2.4 GHz transceiver with higher TX power (+3 dBm), supports ZigBee 3.0 and Thread. | Targets full-featured smart home hubs and battery-powered sensors needing long-range and multi-protocol flexibility. | Choose JN5169 when upgrading to future-proof, multi-standard platforms beyond RF4CE-only remotes. |
Compared with MC13233CR2, CC2530F256 offers more FLASH and mature ZigBee tooling but lacks integrated balun support and PPD_RX optimization; JN5169 delivers ARM performance and protocol breadth but increases BOM cost and power consumption - making MC13233CR2 optimal for cost-constrained, single-protocol RF4CE remotes.

FAQ
What is the primary RF standard supported by the MC13233CR2?
The MC13233CR2 implements the IEEE 802.15.4-2006 standard for 2.4 GHz O-QPSK physical and MAC layers. It natively supports RF4CE (ZigBee BeeStack Consumer), SynkroRF, and proprietary protocols - with hardware acceleration for sequence management, frame filtering, and AES-128 encryption. The MC13233CR2 does not support Bluetooth, Wi-Fi, or sub-GHz protocols.
Does the MC13233CR2 include an integrated balun interface?
Yes, the MC13233CR2 features a differential RF input/output port (RF_INP/RF_INN) designed for direct connection to an external balun. This eliminates the need for discrete matching components and a separate transmit/receive switch - reducing RF layout complexity and BOM cost. The MC13233CR2 datasheet confirms this architecture in Section 3.1 and Figure 1.
What is the lowest power consumption mode available on the MC13233CR2?
The MC13233CR2 achieves <1 μA in STOP3 mode, where system clocks are halted and the internal voltage regulator enters standby while retaining RAM content and enabling fast wake-up. This mode is ideal for battery-powered remotes awaiting keypress interrupts. The MC13233CR2 also supports PPD_RX mode for reduced current during RF listening - further extending operational life.
Can the MC13233CR2 operate without an external 32 MHz crystal?
No - the MC13233CR2 requires an external 32 MHz crystal connected to XTAL32M/XTAL32M_N pins for IEEE 802.15.4 timing compliance (±40 ppm). While it includes an internal 1 kHz oscillator for basic wake-up timing, the 32 MHz reference is mandatory for RF carrier generation, MAC timing, and protocol synchronization. The MC13233CR2 specification explicitly states this dependency in Section 5.
How many GPIO pins does the MC13233CR2 provide, and what peripheral functions are shared?
The MC13233CR2 provides up to 32 GPIO pins across four ports (PTA–PTD), with PTA2 designated output-only. Shared functions include KBI1/KBI2 for keyboard matrix scanning, SPI/I²C/SCI for serial communication, TPM channels for PWM/timing, and CMT for IR carrier generation. Pin multiplexing is controlled via register configuration - allowing flexible allocation per application needs in the MC13233CR2 design.
