Product details
Overview
SPC5514GBMLQ66 from NXP Semiconductors (formerly Freescale) is a 32-bit Power Architecture™ automotive microcontroller designed for central body control and gateway applications. It features an e200z1 main CPU core, 512 KB on-chip flash memory, 32 KB SRAM, 6x FlexCAN interfaces, and operates at up to 66 MHz in the 144-pin LQFP package. It targets vehicle body electronics modules requiring real-time I/O management, CAN routing, and low-power sleep modes.
For engineers reviewing the SPC5514GBMLQ66 datasheet, SPC5514GBMLQ66 pinout, SPC5514GBMLQ66 application, or SPC5514GBMLQ66 equivalent, key selection criteria include its 66 MHz max frequency in LQFP-144, 6-channel FlexCAN support with configurable buffers, eMIOS200 timed I/O module, integrated VREG for single 5 V supply operation, and SLEEP/STOP power modes with selectable RAM retention down to 8 KB.
Technical Context
The SPC5514GBMLQ66 implements a dual-core architecture with an e200z1 main processor and optional e200z0 I/O processor, both compliant with Power Architecture Book E and supporting Variable Length Encoding (VLE) for reduced code footprint. Its crossbar switch enables concurrent access to flash, SRAM, and peripherals by multiple bus masters including CPU, I/O processor, eDMA, and FlexRay.
It integrates a frequency-modulated PLL (FMPLL) with lock detection and loss-of-clock monitoring, a 12-bit ADC with 40 channels (16 input-only, 24 bidirectional), and six independent FlexCAN modules supporting CAN 2.0A/B protocols. The SIU provides four-level pin multiplexing across 111 GPIOs, with per-pin configuration of pull-up/down, slew rate, hysteresis, and open-drain capability.

Pinout & Package
SPC5514GBMLQ66 is housed in a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow Freescale's MPC5510 family pin multiplexing scheme, where each pin supports up to four functional layers (e.g., GPIO, SCI, DSPI, CAN). Full pin mapping requires reference to the MPC5514 Reference Manual (MPC5514RM).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_IO | I/O Power Supply | Supplies 3.3 V or 5.0 V to I/O banks; three independent domains allow mixed-voltage interface design without level shifters. |
| VDD_CORE | Core Power Supply | 1.5 V regulated input for CPU, memory, and logic; derived internally from 5 V VDD via on-chip VREG. |
| VRST_B | Reset Input (Active Low) | Asynchronous reset pin; initiates cold boot sequence and clears all registers and memory contents. |
| OSC_IN / OSC_OUT | Crystal Oscillator Interface | Supports external 32 kHz crystal for RTC and low-power wakeup; also accepts 4–40 MHz reference for FMPLL. |
| CAN0_TX / CAN0_RX | FlexCAN Channel 0 Interface | Differential CAN physical layer signals; require external transceiver (e.g., TJA1042) for bus connection. |
| DSPI0_SIN / DSPI0_SOUT / DSPI0_SCK / DSPI0_PCS0 | Dual SPI Module 0 Signals | Full-duplex synchronous serial interface; supports daisy-chain or multi-slave configurations with hardware chip select. |
| ADC0[0]–ADC0[15] | Analog Input Channels | 16 dedicated analog inputs (12-bit resolution); support voltage measurement for battery monitoring, temperature, and potentiometer feedback. |
| SIUL_GPIO[0]–SIUL_GPIO[110] | General-Purpose I/O | 111 programmable pins with software-configurable direction, drive strength, pull type, and digital filtering for noise immunity. |
Key Features
| Feature | Design Value |

FAQ
What is the maximum operating frequency of the SPC5514GBMLQ66?
The SPC5514GBMLQ66 operates at a maximum frequency of 66 MHz when packaged in the 144-pin LQFP variant and tested at ambient temperatures up to 105°C. This speed is guaranteed under full load conditions and forms the basis for real-time scheduling in body control applications. The SPC5514GBMLQ66 uses an e200z1 core with VLE support, ensuring deterministic instruction timing critical for safety-related functions.
Does the SPC5514GBMLQ66 include an integrated voltage regulator?
Yes, the SPC5514GBMLQ66 integrates an on-chip voltage regulator (VREG) that accepts a single 5 V ±10% supply and generates the required 1.5 V core voltage. This eliminates the need for external DC/DC converters in many body electronics designs. The VREG also supplies regulated I/O voltage domains, supporting mixed 3.3 V and 5.0 V interfaces directly from the SPC5514GBMLQ66's VDD_IO pins.
How many CAN interfaces does the SPC5514GBMLQ66 support?
The SPC5514GBMLQ66 supports six independent FlexCAN modules (CAN0–CAN5), each compliant with CAN 2.0A/B protocols. These are fully configurable with dedicated message buffers and acceptance filtering, enabling concurrent communication across multiple vehicle networks - such as HS CAN for powertrain, LS CAN for body, and diagnostic CAN. The SPC5514GBMLQ66's six-channel capability makes it ideal for gateway applications requiring message routing and protocol translation.
What low-power modes are available on the SPC5514GBMLQ66?
The SPC5514GBMLQ66 offers three primary low-power modes: RUN (full performance), STOP (clocks halted, full RAM/state retained), and SLEEP (power-gated, selective RAM retention). In SLEEP mode, designers can retain 8 KB, 16 KB, 32 KB, 64 KB, or full 32 KB SRAM while drawing as little as 25–95 μA depending on configuration. Wake-up sources include CAN activity, GPIO edges, RTC alarms, and internal oscillators - all supported natively by the SPC5514GBMLQ66's power management unit.
Is the SPC5514GBMLQ66 pin-compatible with other MPC5510 family members?
No, the SPC5514GBMLQ66 is not pin-compatible with other MPC5510 variants due to differing package footprints and pin multiplexing configurations. While it shares the 144-LQFP package with MPC5514E and MPC5516E, the specific peripheral assignments (e.g., CAN channel mapping, DSPI chip selects, ADC channel availability) vary significantly. Migration requires PCB redesign and firmware adaptation. The SPC5514GBMLQ66's pinout must be validated against the MPC5514 Reference Manual before layout.
