Product details
Overview
MMA9559LR1 from NXP Semiconductors (formerly Freescale) is an intelligent 3-axis motion-sensing platform integrating a MEMS accelerometer, 32-bit ColdFire V1 CPU, 16 KB flash, 2 KB RAM, and dual I²C interfaces. It operates at 1.8 V, supports ±2/±4/±8 g ranges, and delivers programmable ODR from 3.8 Hz to 488 Hz. Designed for embedded sensor-hub applications, it offloads motion processing from host processors in portable electronics.
For engineers reviewing the MMA9559LR1 datasheet, MMA9559LR1 pinout, MMA9559LR1 application, or MMA9559LR1 equivalent, this page provides verified technical context, validated pin functions, confirmed firmware-specific capabilities (e.g., event management, inter-process FIFO), and real-world integration guidance for motion-aware system design.
Technical Context
The MMA9559LR1 implements a dedicated mixed-signal ASIC with analog front-end (capacitance-to-voltage converter + 10–16-bit ADC), integrated temperature sensor, and digital subsystem centered on a 32-bit ColdFire V1 core with MAC unit. Its architecture separates slave I²C/SPI communication (operational during deep-sleep) from CPU execution, enabling always-on sensor arbitration without host wake-up.
Unlike MMA9550L/9551L/9553L variants, the MMA9559LR1 omits factory-loaded gesture/pedometer firmware and instead enables full user-programmable control loops via CodeWarrior IDE. It uniquely supports event management, inter-process FIFO, and programmable delay block scheduling - features absent in other family members per Table 2 of the datasheet.

Equivalent & Alternatives
The following parts are listed as comparable options for similar intelligent motion-sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMA9553LR1 | Factory-loaded pedometer firmware; 1.0 KB user flash; no event management or inter-process FIFO | Preconfigured step counting only; no custom algorithm support | Select when rapid time-to-market for basic activity tracking is required without firmware development |
| BMI270 | Integrated 6-axis IMU (gyro + accel); 512-byte FIFO; no embedded MCU; requires external host for motion processing | Host-dependent sensor fusion; higher power in active state; no autonomous decision-making | Select when gyro-augmented motion sensing is needed and host processor has capacity for real-time fusion |
Compared with MMA9553LR1, the MMA9559LR1 trades preloaded functionality for full programmability and real-time event handling; compared with BMI270, it embeds decision logic on-chip but lacks integrated gyroscope - making it optimal for cost-sensitive, host-offload motion hubs where algorithm flexibility outweighs multi-axis sensing.

FAQ
What distinguishes MMA9559LR1 from other MMA955xL family members like MMA9553LR1?
The MMA9559LR1 is the foundation firmware variant - it contains no preloaded motion applications and instead provides maximum user flash (14 KB) and RAM (1664 bytes) for custom firmware development. Unlike MMA9553LR1 (pedometer-optimized) or MMA9551LR1 (gesture-optimized), the MMA9559LR1 uniquely supports event management, inter-process FIFO, and programmable delay block scheduling - all required for building proprietary real-time motion control loops. It requires CodeWarrior IDE programming and does not operate out-of-box.
Does MMA9559LR1 support both I²C and SPI interfaces simultaneously?
No - the MMA9559LR1 supports either I²C or SPI as its slave interface, selected at power-up via the RGPIO3/SDA1/SSB pin level. High at startup configures slave I²C (default 7-bit address 0x4C); low configures slave SPI. The master I²C interface (SCL1/SDA1) operates independently and concurrently for external sensor communication, but the slave port is exclusively one protocol at boot.
What is the role of the BKGD-MS pin on MMA9559LR1 and how is it used in production?
The BKGD-MS pin serves dual roles: mode selection at power-up and single-wire Background-Debug Mode (BDM) interface. During startup, it determines boot path - high for application code, low for BDM. In production, it is typically left floating (relying on internal pullup) or tied high for normal operation. For firmware updates or debugging, it connects to a BDM programmer (e.g., P&E Multilink) to download code into flash or RAM without JTAG, enabling field reprogramming with minimal footprint.
Can MMA9559LR1 perform analog signal acquisition alongside accelerometer data?
Yes - the MMA9559LR1 integrates a 16-bit ADC with differential inputs on pins AN0 (−) and AN1 (+), supporting up to 1.8 V full-scale differential range. Analog conversions are synchronized to the same Output Data Rate (ODR) as the accelerometer, enabling time-aligned acquisition of external sensor signals (e.g., EMG, pressure transducers) alongside motion data - critical for multi-modal health or industrial monitoring applications.
How does MMA9559LR1 achieve ultra-low power consumption in always-on motion sensing?
The MMA9559LR1 achieves ultra-low power by combining hardware autonomy with intelligent power gating: its slave I²C/SPI interface remains active during deep-sleep (0.9 µA typical), allowing host wake-up only on interrupt (e.g., RGPIO4/INT or INT_O). Internal event management and programmable delay block eliminate polling, while the 32-bit CPU executes motion algorithms only when triggered - reducing average current to 12 µA in typical activity-monitoring use cases, versus >100 µA for host-driven alternatives.
