MC1323x Advance Information, Rev. 1.2 Freescale Semiconductor 5 2.3.3 SynkroRF Platform The SynkroRF Network is a general purpose, proprietary networking layer that sits on top of the IEEE® 802.15.4 MAC and PHY layers. It is designed for Wireless Personal Area Networks (WPANs) and conveys information over short distances among the participants in the network. It enables small, power efficient, inexpensive solutions to be implemented for a wide range of applications. Some key characteristics of an SynkroRF Network are: • An over-the-air data rate of 250 kbit/s in the 2.4 GHz band. • 3 independent communication channels in the 2.4 GHz band (15, 20, and 25). • 2 network node types, controller and controlled nodes. • Channel Agility mechanism. • Low Latency Tx mode automatically enabled in conditions of radio interference. • Fragmented mode transmission and reception, automatically enabled in conditions of radio interference. • Robustness and ease of use. • Essential functionality to build and support a CE network.

MC1323x Advance Information, Rev. 1.2 6 Freescale Semiconductor 2.3.5 ZigBee-Compliant Network Stack Freescale’s BeeStack architecture builds on the ZigBee protocol stack. Based on the OSI Seven-Layer model, the ZigBee stack ensures inter-operability among networked devices. The physical (PHY), media access control (MAC), and network (NWK) layers create the foundation for the application (APL) layers. BeeStack defines additional services to improve the communication between layers of the protocol stack. At the Application Layer, the application support layer (ASL) facilitates information exchange between the Application Support Sub-Layer (APS) and application objects. Finally, ZigBee Device Objects (ZDO), in addition to other manufacturer-designed applications, allow for a wide range of useful tasks applicable to home and industrial automation. BeeStack uses the IEEE 802.15.4-compliant MAC/PHY layer that is not part of ZigBee itself. The NWK layer defines routing, network creation and configuration, and device synchronization. The application framework (AF) supports a rich array of services that define ZigBee functionality. ZigBee Device Objects (ZDO) implement application-level services in all nodes via profiles. A security service provider (SSP) is available to the layers that use encryption (NWK and APS), i.e., Advanced Encryption Standard (AES) 128-bit security. The complete Freescale BeeStack protocol stack includes the following components: • ZigBee Device Objects (ZDO) and ZigBee Device Profile (ZDP) • Application Support Sub-Layer (APS) • Application Framework (AF) • Network (NWK) Layer • Security Service Provider (SSP) • IEEE 802.15.4-compliant MAC and Physical (PHY) Layer 3 Integrated IEEE 802.15.4 Transceiver (Radio and Modem) The MC1323x IEEE 802.15.4 fully-compliant transceiver provides a complete 2.4 GHz radio with 250 kbps Offset-Quadrature Phase Shift Keying (O-QPSK) data in 5.0 MHz channels and full spread-spectrum encode and decode. The modem supports the full requirement of the IEEE 802.15.4 Standard functionality to transmit, receive, and do clear channel assessment (CCA), Energy Detect (ED), and Link Quality Indication (LQI). • Programmable output power with 0 dBm nominal output power, programmable from -30 dBm to +2 dBm typical • Receive sensitivity of -94 dBm (typical) at 1% PER, 20-byte packet • Differential bi-directional RF input/output port • Integrated transmit/receive switch • Receive current can be reduced while waiting or “listening” for an incoming frame using partial power down (PPD) mode MC1323x Advance Information, Rev. 1.2 Freescale Semiconductor 7 3.1 RF Interface and Usage The MC1323x RF interface provides a bi-directional, differential port that connects directly to a balun. The balun connects directly to a single-ended antenna and converts that interface to a full differential, bi-directional, on-chip interface with transmit/receive switch, LNA, and complementary PA outputs.This combination allows for a small footprint and low cost RF solution. 3.2 Transceiver Register Interface and Operation The transceiver is controlled by set of interface registers that are memory-mapped into the CPU address space. The transceiver is capable of independent operation to perform transmit, receive, or perform CCA/ED operations and combinations. Additional features of the transceiver include: • DMA function moves data directly between RAM and transceiver buffers during transmit and receive on a cycle-steal basis. This off loads the data transfer from the CPU and provides higher performance. • Interrupt capability dependent on RX packet data availability. An interrupt can be generated based on a programmed count of RX data bytes that have been received and moved to RAM. This allows CPU filtering of RX data before completion of the packet reception to accelerate response to the packet. • Four transceiver Event Timer comparators are available to supplement MCU peripheral timer resources for PHY and MAC timing requirements. 3.3 IEEE 802.15.4 Acceleration Hardware The 802.15.4 transceiver has several hardware features that reduce the software stack size, off load the function from the CPU, and improve performance • Fully supports 2003 & 2006 versions of the IEEE 802.15 Standard. • Supports slotted and unslotted modes • Supports beacon enabled and non-beacon enabled networks • DMA data transfer between RAM and radio • Separate AES-128 Security module • 16-bit random number generator • 802.15.4 Sequence support — RX (conditionally followed by TXAck) — TX — CCA (used for CCA and ED cycles) — Tx/Rx (Tx followed by unconditional Rx or RCACK) — Continuous CCA • 802.15.4 Receiver Frame filtering. MC1323x Advance Information, Rev. 1.2 8 Freescale Semiconductor 3.4 Unique Partial Power Down (PPD) or “Listen” Receive Mode The MC1323x provides a unique Partial Power Down receive (PPD_RX) mode. When this mode is selected: • Whenever a receive cycle is initiated, the receiver is not turned fully on to save current until receive energy of a preset level is detected • The receiver will turn fully on only when triggered by energy at the preset level, and then receives the expected frame. The full-on state is the same as the standard receive state • The preset level can be programmed for various RX input power levels Use of the PPD_RX mode provides two distinct advantages: 1. Reduced “listen” mode current - The receive current is significantly reduced while waiting for a frame. If a node is a coordinator, router, or gateway and it spends a significant percentage of its RF-active time waiting for incoming frames from clients or other devices, the net power savings can be significant. 2. Reduced sensitivity as a desired effect - The PPD_RX mode provides different levels of reduced sensitivity. If a node operates in a densely populated area, it may be desirable to de-sensitize the receiver such that the device does not respond to incoming frames with an energy level below the desired threshold. This could be useful for security, net efficiency, reduced noise triggering and many other purposes. 4 HCS08 8-Bit Central Processing Unit (CPU) The onboard CPU is a 32 MHz 8-bit HCS08 core. It executes a super set of the 68HC08 instruction set with added BGND instructions. The HCS08 CPU is fully source and object code compatible with the M68HC08 CPU. Several instructions and enhanced addressing modes are added to improve C compiler efficiency and to support a new background debug system. It has an 8-bit data bus, a 16-bit address bus and a 2-stage instruction pipe that facilitates the overlapping of instruction fetching and execution. There are 29 vectors for internal interrupt sources and one vector for an external interrupt pin. The debug or BDM module provides a serial one-wire interface for non-intrusive debugging of application programs.

The crystal requirements for the oscillator and oscillator performance must support a +/-40 ppm frequency accuracy to meet the IEEE 802.15.4 Standard requirements. All system clocks are generated from this source. Features of the clock system include: • The 32 MHz reference oscillator has onboard programmable capacitive loading that allows software tuning of frequency accuracy • CPU clock as high as 32 MHz • Bus clock (and peripheral clock) equals 1/2 CPU clock • Clocks to individual peripherals can be independently disabled for best power management. • CPU clock can be lowered to 500 kHz for lower power (250 kHz bus clock) An optional 32.768 kHz crystal oscillator is available for accurate low power timing and the Real Time Clock (RTC). Also, an onboard, low accuracy 1 kHz oscillator is available for sleep timing wake-up. 6 Memory The MC1323x memory resources consist of RAM, FLASH program memory for nonvolatile data storage, and control/status registers for I/O, peripherals, management, and the transceiver. Features include: • 80 KB FLASH (81920dec) bytes organized as 80 segments of 1024 byte/segment) • 5 KB RAM • Security circuitry to prevent unauthorized access to RAM and FLASH contents MC1323x Advance Information, Rev. 1.2 10 Freescale Semiconductor 7 System and Power Management The MC1323x is inherently a low power device, but it also has extensive system control and power management to maximize battery life and provide system protection. 7.1 Modes of Operation The MC1323x modes of operation include: • Active background mode for code development • Run mode — CPU clocks can be run at full speed and the internal supply is fully regulated. • LPRun mode — CPU clock is set to 500 kHz and peripheral clocks (bus clock) to 250 kHz and the internal voltage regulator is in standby • Wait mode — CPU shuts down to conserve power; system clocks are running and full regulation is maintained • LPWait mode — CPU shuts down to conserve power; peripheral clocks are restricted to 250 kHz and the internal voltage regulator is in standby • STOP modes — System clocks are stopped and voltage regulator is in standby — STOP3 — All internal circuits are powered for fast recovery (32 MHz oscillator on-off optional) — STOP2 — Partial power down of internal circuits, RAM content is retained; I/O states are held 7.2 Power Management The MC1323x power management is controlled through programming of the modes of operation.

MC1323x Advance Information, Rev. 1.2 Freescale Semiconductor 11 7.3 System Protection The MC1323x provides several vehicles to maintain security or a high level of system robustness: • Watchdog computer operating properly (COP) reset with option to run from dedicated internal clock source or bus clock • Low-voltage warning and detection with reset or interrupt; selectable trip points • Illegal opcode detection with reset • FLASH block protection 8 MCU Peripherals The MC1323x has a functional set of MCU peripherals focused for intended applications. 8.1 Parallel Input/Output (GPIO) The MC1323x has four I/O ports that provide up to 31 general-purpose I/O signals and 1 output only signal. Many of these pins are shared with on-chip peripherals such as timer systems, communication ports, or keyboard interrupts. When these other modules are not controlling the port pins, they revert to general-purpose I/O control. For each I/O pin, a port data bit provides access to input (read) and output (write) data, a data direction bit controls the direction of the pin, and a pullup enable bit enables an internal pullup device (provided the pin is configured as an input), and a slew rate control bit controls the rise and fall times of the pins.Parallel I/O features include Parallel I/O features include: • A total of 32 general-purpose I/O pins in four ports (PTA2 is output only) • Hysteresis input buffers • Software-controlled pull-ups on each input pin • Software-controlled slew rate output buffers • Eight port A pins shared with 32.768 kHz oscillator, IRQ, IIC, and BKGD • Eight port B pins shared with KBI1[7:0] • Eight port C pins shared with KBI2[3:0] and SPI • Eight port D pins shared with TPM0, TPM1, TPM2, TPM3, CMT (with 20mA drive), UART, and 32MOUT (reference frequency clock output) 8.2 Keyboard Interrupt Modules (KBI) The MC1323x has two KBI modules; KBI1 shares eight Port A pins and KBI2 shares the lower four pins of Port C. Any KBI pin can be enabled as a keyboard input that can act as an interrupt request. As a result, the total 12 KBI inputs allows as large as a 12x12 keyboard matrix with use of other GPIO pins as outputs to the matrix. All enabled KBI inputs can be configured for edge-only sensitivity or edge-and-level sensitivity. They also can be configured for either rising edge / high-level or falling-edge/low-level sensitivity. When enabled MC1323x Advance Information, Rev. 1.2 12 Freescale Semiconductor for rising edge / high level sensitivity, a pulldown resistor is enabled, and when enabled for falling edge / low level sensitivity, a pull-up resistor is enabled. The KBI features include: • KBI1 has eight keyboard interrupt pins with individual pin enable bits. • KBI2 has four keyboard interrupt pins with individual pin enable bits. • Supports up to a 12x12 keyboard matrix. A 6x6 matrix can be supported without impacting other I/O functions. • Each keyboard interrupt pin is programmable as falling edge (or rising edge) only, or both falling edge and low level (or both rising edge and high level) interrupt sensitivity. Pull-ups and pull-downs enabled by selected mode. • Individual signal software enabled interrupts for both KBI1 and KBI2. • Can be used for device wake-up 8.3 Serial Communications Interface (SCI) Module The MC1323x has one serial communications interface module — sometimes called a universal asynchronous receiver/transmitter (UART). Typically, this port is used to connect to the RS232 serial input/output (I/O) port of a personal computer or workstation, and it can also be used to communicate with other embedded controllers. The SCI module has a single, flexible frac-N (13-bit modulo counter, 5-bit fractional counter) baud rate generator used both for transmit and receive. With a maximum 16 MHz peripheral clock, baud rates as high as 1 Mbps can be supported (standard is 921,600 baud). This SCI system offers many advanced features not commonly found on other asynchronous serial I/O peripherals on other embedded controllers. The receiver employs an advanced data sampling technique that ensures reliable communication and noise detection. Hardware parity, receiver wake-up, and double buffering on transmit and receive are also included. Features of SCI module include: • Full-duplex, standard non-return-to-zero (NRZ) format • Double-buffered transmitter and receiver with separate enables • Programmable high accuracy baud rates (frac-N generator) • Interrupt-driven or polled operation: — Transmit data register empty and transmission complete — Receive data register full — Receive overrun, parity error, framing error, and noise error — Idle receiver detect — Active edge on receive pin — Break detect supporting LIN • Hardware parity generation and checking • Programmable 8-bit or 9-bit character length MC1323x Advance Information, Rev. 1.2 Freescale Semiconductor 13 • • • 8.4 Receiver wake-up by idle-line or address-mark Optional 13-bit break character generation / 11-bit break character detection Selectable transmitter output polarity Serial Peripheral Interface (SPI) Module The MC1323x has one serial peripheral interface module. The SPI is a synchronous serial data input/output port used for interfacing with serial memories, peripheral devices, or other processors. The SPI allows an 8-bit serial bit stream to be shifted simultaneously into and out of the device at a programmed bit-transfer rate (called 4-wire mode). There are four pins associated with the SPI port (SPCLK, MOSI, MISO, and SS). The SPI module can be programmed for master or slave operation. It also supports a 3-wire mode where for master mode the MOSI becomes MOMI, a bidirectional data pin, and for slave mode the MISO becomes SISO, a bidirectional data pin. In 3-wire mode, data is only transferred in one direction at a time. The SPI bit clock is derived from the peripheral input clock with a maximum 16 MHz operation. A programmable prescaler (maximum divide-by-8) drives a second baud rate programmable divider (maximum divide-by-256) to develop the bit clock. The maximum SPI transfer rate is 8 MHz. Features of SPI module include: • Master or slave mode operation • Full-duplex or single-wire bidirectional option • 8-Bit only transfer size • Programmable transmit bit rate (8 MHz max) • Double-buffered transmit and receive • Serial clock phase and polarity options (supports all 4 options) • Optional slave select output • Selectable MSB-first or LSB-first shifting 8.5 Inter-integrated Circuit (IIC) Interface Module The MC1323x has one inter-integrated circuit interface module that provides a method of communication between a number of other integrated circuits. The IIC Bus interface provides a bidirectional, 2-pin (SDA bus data and SCL bus clock) serial bus designed to operate up to 100 kbps with maximum bus loading and timing. The module is capable of operating at higher baud rates, up to a maximum of peripheral clock/20 (800 kbps), with reduced bus loading. Features of IIC module include: • Compatible with IIC bus standard • Multi-master operation • Software programmable clock frequencies • Software selectable acknowledge bit • Interrupt driven byte-by-byte data transfer MC1323x Advance Information, Rev. 1.2 14 Freescale Semiconductor • • • • • • • • 8.6 Arbitration lost interrupt with automatic mode switching from master to slave Calling address identification interrupt START and STOP signal generation/detection Repeated START signal generation Acknowledge bit generation/detection Bus busy detection General call recognition 10-bit address extension Timer/PWM (TPM) Modules The MC1323x has four independent timer/PWM modules, each with one channel. Each TPM module is based on a 16-bit counter and provides input capture, output compare, and pulse width modulation. Each TPM module has one associated I/O pin for input capture or counter/PWM output. TPM module features include: • • • • • • • • 8.7 Each TPM may be configured for buffered, center-aligned pulse-width modulation (CPWM) on all channels Module clock source is always peripheral clock Clock prescaler taps for divide by 1, 2, 4, 8, 16, 32, 64, or 128 16-bit free-running or up/down (CPWM) count operation 16-bit modulus register to control counter range Module enable One interrupt per channel plus a terminal count interrupt for each TPM module Channel features: — Each channel may be input capture, output compare, or buffered edge-aligned PWM — Rising-edge, falling-edge, or any-edge input capture trigger — Set, clear, or toggle output compare action — Selectable polarity on PWM outputs Carrier Modulator Timer (CMT) Module The MC1323x carrier modulator timer module is intended as an IR LED driver for remote control “blaster” applications. The module consists of a carrier generator, modulator, and transmitter that drives data to the output (IRO) pin either in baseband or in FSK mode. The IRO pin drives (modulates) the IR diode directly or through a buffer depending on the required current. The IRO pin is specified for 20mA drive. The CMT module features include: • Four modes of operation — Time with independent control of high and low times — Baseband MC1323x Advance Information, Rev. 1.2 Freescale Semiconductor 15 • • • • 8.8 — Frequency shift key (FSK) — Direct software control of IRO pin Extended space operation in time, baseband, and FSK modes Module clock source is peripheral clock (16 MHz max) Interrupt on end of cycle Ability to disable IRO pin and use as timer interrupt Real-time Counter (RTC) Module The MC1323x real-time counter module consists of one 16-bit counter, one 16-bit comparator, several binary-based and decimal-based prescaler dividers, three clock sources, and one programmable periodic interrupt. This module can be used for time-of-day, calendar or any task scheduling functions. It can also serve as a cyclic wake-up from low power modes (STOP2, STOP3 and WAIT). RTC can be clocked from bus clock, the optional 32.768 kHz oscillator or the onboard 1 kHz low power oscillator. Features of the RTC module include: • 16-bit up-counter — 16-bit modulo match limit — Software controllable periodic interrupt on match • Three software selectable clock sources for input to prescaler with programmable 16 bit prescaler — 32.768 kHz optional crystal oscillator. — 32 MHz reference oscillator — 1 kHz low power RC oscillator • Useful for time base tick or time-of-day clock • Can be used for device wake-up; capable of greater than one day time-out period. 9 Development Environment Development support for the HCS08 on the MC1323x includes the background debug controller (BDC) and the on-chip debug module (DBG). The BDC provides a single-wire (signal BKGD) debug interface to the MCU that provides a convenient interface for programming the on-chip FLASH and other storage. The BDC is also the primary debug interface for development and allows non-intrusive access to memory data and traditional debug features such as CPU register modify, breakpoints, and single instruction trace commands. Address and data bus signals are not available on external pins. Debug is done through commands fed into the MCU via the single-wire background debug interface. The debug module provides a means to selectively trigger and capture bus information so an external development system can reconstruct what happened inside the MCU on a cycle-by-cycle basis without having external access to the address and data signals. Features include: • Single-wire background debug interface MC1323x Advance Information, Rev. 1.2 16 Freescale Semiconductor • • • Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints in on-chip debug module) On-chip in-circuit emulator (ICE) debug module containing three comparators and nine trigger modes. Eight deep FIFO for storing change-of-flow addresses and event-only data. Debug module supports both tag and force breakpoints. 10 Pin Assignment and Connections 10.1 Device Pin Assignment Figure 2.

MC1323x Advance Information, Rev. 1.2 Freescale Semiconductor 19 11 Electrical Specifications This section details maximum ratings for the 48-pin LGA package, recommended operating conditions, DC characteristics, and AC characteristics. 11.1 Package Maximum Ratings Absolute maximum ratings are stress ratings only, and functional operation at the maximum rating is not guaranteed. Stress beyond the limits specified in Table 3 may affect device reliability or cause permanent damage to the device. For functional operating conditions, refer to the remaining tables in this section. This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, it is advised that normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for instance, either VSS or VBATT) or the programmable pull-up resistor associated with the pin is enabled. Table 3 shows the maximum ratings for the 48-Pin LGA package. Table 3.

Functional operation should be restricted to the limits in the Electrical Characteristics or Recommended Operating Conditions tables. Note: Meets ESD Human Body Model (HBM) = 2 kV 11.2 ESD Protection and Latch-Up Immunity Although damage from electrostatic discharge (ESD) is much less common on these devices than on early CMOS circuits, normal handling precautions should be used to avoid exposure to static discharge. Qualification tests are performed to ensure that these devices can withstand exposure to reasonable levels of static without suffering any permanent damage. All ESD testing is in conformity with the JESD22 Stress Test Qualification for Commercial Grade Integrated Circuits. During the device qualification ESD stresses were performed for the human body model (HBM), the machine model (MM) and the charge device model (CDM). MC1323x Advance Information, Rev. 1.2 20 Freescale Semiconductor All latchup test testing is in conformity with the JESD78 IC Latch-Up Test.
