Product details
Overview
MC13211R2 from NXP (formerly Freescale) is a ZigBee-compliant system-in-package integrating a 2.4 GHz IEEE 802.15.4 transceiver and HCS08 MCU in a single 71-pin LGA. It delivers 16 KB flash, 1 KB RAM, -92 dBm receive sensitivity, 0 dBm nominal output power, and supports proprietary point-to-point/star networks using Freescale Simple MAC (SMAC). It targets low-cost residential automation and wireless sensor nodes.
For engineers reviewing the MC13211R2 datasheet, MC13211R2 pinout, MC13211R2 application, or MC13211R2 equivalent, this page provides verified technical context, validated pin functions, confirmed RF and MCU specifications, real-world use cases for lighting control and AMR, and two documented alternative parts with precise functional and memory differences.
Technical Context
The MC13211R2 implements a tightly coupled SIP architecture where the HCS08 CPU core (40 MHz max) communicates exclusively with the 802.15.4 modem via a dedicated internal SPI interface operating up to 8 MHz. The modem includes an integrated T/R switch, on-chip VCO with programmable trim, and dual PA outputs supporting external LNA/PA configurations.
It features dual clock domains: a 16 MHz crystal drives the modem's reference oscillator (with onboard trimming), while CLKO provides programmable frequencies (16/8/4/2/1 MHz, 62.5 kHz, 32.786+ kHz) to synchronize the MCU - enabling single-crystal system operation. Power management includes Stop2/Stop3 low-power modes and hardware-based attention wake-up (ATTN).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Standard | IEEE 802.15.4-2003 compliant O-QPSK at 250 kbps in 2.4 GHz ISM band with 16 selectable channels |
| Output Power | 0 dBm nominal; programmable from –27 dBm to +3 dBm typical - enables range/power trade-off tuning |
| Receive Sensitivity | –92 dBm (typical) at 1% PER, 20-byte packet - exceeds 802.15.4 standard (–85 dBm) by 7 dB |
| MCU Core | HCS08 Version A, 40 MHz max CPU frequency with background debug module (BDM) for in-circuit programming |
| Memory | 16 KB on-chip flash (block-protected, secure), 1 KB RAM - sufficient for SMAC stack and lightweight sensor applications |
| Supply Voltage | 2.0 V to 3.4 V operation with integrated voltage regulators for analog/digital/RF domains - simplifies external power design |
| Operating Temp | –40°C to +85°C - qualified for industrial and residential embedded environments |
Pinout & Package
MC13211R2 uses a 9 mm × 9 mm × 1 mm 71-pin LGA package (Case 1664-01), with exposed thermal pad. Pin functions are validated per Freescale Document MC1321x Rev. 1.8, including dedicated SPI interconnects, RF I/O (RFIN_P/M, PAO_P/M), and dual-domain GPIO (MCU and modem).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PTG1/XTAL & PTG2/EXTAL | Modem crystal oscillator interface | Drive 16 MHz fundamental-mode crystal; XTAL2 output not usable as clock source - CLKO must be used instead |
| CLKO | Programmable clock output | Provides MCU clock source at 16/8/4/2/1 MHz or sub-MHz rates - enables single-crystal system architecture |
| RFIN_P / RFIN_M | Differential RF input/output | Bidirectional ports for internal LNA/PA when T/R switch enabled; require 50 Ω matching network |
| PAO_P / PAO_M | Differential RF power amplifier output | Open-drain outputs requiring external bias network to VDDA - used only with external balun or PA |
| ATTN | Active-low wake-up input | Drives modem from Hibernate/Doze to Idle mode - must remain driven during low-power states |
| PTE2/SS1, PTE3/MISO1, PTE4/MOSI1, PTE5/SPSCK1 | Internal SPI interface | Dedicated MCU-to-modem SPI bus; CE, MISO, MOSI, SPICLK - factory-test pins; not for user routing |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 802.15.4 Transceiver + HCS08 MCU | Eliminates external RF IC and separate microcontroller - reduces BOM count and PCB area in compact wireless nodes |
| On-chip crystal oscillator trim | Removes need for external variable capacitors and enables automated production calibration of 16 MHz reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2.4 GHz ZigBee/802.15.4 SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC13212R2 | 32 KB flash, 2 KB RAM, supports full 802.15.4 MAC - no SMAC-only limitation | Required for mesh networking, beaconed topologies, or GTS-based low-latency applications | Select MC13212R2 when migrating from proprietary SMAC to standards-based 802.15.4 networks with coordinator/router roles. |
| CC2530F128 | 8051 core, 128 KB flash, 8 KB RAM, integrated balun, 4.5 dBm output - higher RF performance but larger footprint | Suitable for longer-range or higher-throughput ZigBee HA/SE deployments requiring AES-128 and full stack support | Choose CC2530F128 when greater memory headroom, integrated RF front-end, or TI Z-Stack compatibility is mandatory. |
Compared with MC13212R2 and CC2530F128, the MC13211R2 offers lowest cost and smallest footprint for SMAC-based star networks, but lacks mesh capability and has half the flash of its sibling - making it optimal for fixed-function, battery-constrained endpoints where software overhead is minimized.

FAQ
What is the primary function of the MC13211R2 in a wireless system?
The MC13211R2 integrates an IEEE 802.15.4-compliant 2.4 GHz transceiver and HCS08 microcontroller into a single SIP package. Its primary function is to serve as a complete wireless node - handling RF modulation/demodulation, packet processing, and application logic execution - especially for SMAC-based proprietary star networks in lighting, sensing, and metering applications. The MC13211R2 eliminates the need for discrete RF and MCU components.
Does the MC13211R2 support ZigBee certification out of the box?
No, the MC13211R2 does not support full ZigBee certification natively. It is intended for proprietary applications using Freescale Simple MAC (SMAC) and lacks the 60 KB flash and 4 KB RAM required for BeeStack. Full ZigBee compliance requires the MC13213 variant with BeeStack software. The MC13211R2 supports only 802.15.4 PHY/MAC layer functionality and SMAC - not ZigBee cluster libraries or profile certification.
What are the key power supply requirements for the MC13211R2?
The MC13211R2 requires four distinct supply domains: VBATT (2.0–3.4 V input to RF regulators), VDDA (analog regulated output), VDDINT (digital interface supply), and VDD (MCU core supply). Each must be decoupled per Freescale layout guidelines. VDDA powers RF sections including PAO_P/M and RFIN_P/M; VDDINT feeds digital modem logic; and VDD supplies the HCS08 core. Improper domain isolation causes RF desense or reset instability.
Can the MC13211R2 operate with a single 16 MHz crystal?
Yes, the MC13211R2 supports single-crystal operation. The 16 MHz crystal connects to PTG1/XTAL and PTG2/EXTAL for the modem's reference oscillator, and the CLKO pin delivers programmable clock outputs (16/8/4/2/1 MHz, etc.) to drive the MCU - eliminating need for a second crystal. This configuration is validated in Figure 2 of MC1321x Rev. 1.8 and reduces BOM cost and board space. XTAL2 must not be loaded externally.
How does the MC13211R2 handle RF antenna interface and impedance matching?
The MC13211R2 provides differential RF I/O via RFIN_P/RFIN_M (receive/transmit) and PAO_P/PAO_M (power amplifier output). When using the internal T/R switch, RFIN_P/M connect directly to a 50 Ω balanced antenna or balun. For external PA/LNA, PAO_P/M require a bias network to VDDA and matching to 50 Ω. CT_Bias provides control voltage referencing - critical for proper T/R switching and external component biasing. Layout must maintain tight differential pair symmetry and ground plane integrity.
