NXP Semiconductors SPC5645SF1VLT

Overview

SPC5645SF1VLT from NXP Semiconductors is a 32-bit Power Architecture® e200z4d microcontroller designed for single-chip automotive instrument cluster applications. It integrates 2 MB ECC flash, 64 KB ECC SRAM, 1 MB non-ECC graphics RAM, dual display control units (DCU3 and DCULite), and a 2D OpenVG 1.1 graphics accelerator to drive two color TFT displays up to XGA resolution.

For engineers reviewing the SPC5645SF1VLT datasheet, SPC5645SF1VLT pinout, SPC5645SF1VLT application, or SPC5645SF1VLT equivalent, key selection criteria include its dual-display timing capability, VIU2 video input support, 6-motor stepper motor controller with stall detection, FlexCAN/LINFlex/I²C peripheral count, and STANDBY/STOP low-power mode wake-up latency under 350 µs.

Technical Context

The SPC5645SF1VLT implements a dual-issue e200z4d CPU core with 4 KB instruction cache, MMU, SPE, and EFP2 floating-point unit, operating at up to 125 MHz via FMPLL0. Its crossbar switch enables concurrent access by seven masters-including CPU, eDMA, GFX2D, VIU2, and DCUs-to eight slave resources including flash, SRAM, graphics RAM, QuadSPI, and peripherals.

It features two independent clock domains: FMPLL0 drives system timing (up to 125 MHz), while FMPLL1 supplies modulated/non-modulated clocks to eMIOS, QuadSPI, and pixel clock generation for DCU/DCULite. The device supports three low-power modes-HALT, STOP, and STANDBY-with VREG fast-start (<350 µs) and configurable SRAM retention (8 KB or 64 KB).

FAQ

What is the maximum display resolution supported by the SPC5645SF1VLT?

The SPC5645SF1VLT supports up to XGA resolution (1024 × 768 pixels) per display via its DCU3 and DCULite modules. Both display units operate independently, enabling simultaneous dual-XGA output. The device's 1 MB on-chip graphics RAM and 2D OpenVG 1.1 accelerator ensure real-time rendering at 60 Hz without external frame buffer memory. This capability is confirmed in Section 1.3 and Table 1 of the MPC5645S datasheet Rev. 14.

Does the SPC5645SF1VLT include hardware support for video input?

Yes, the SPC5645SF1VLT integrates a Video Input Unit (VIU2) that supports 8/10-bit ITU-R BT.656 video streams, YUV-to-RGB conversion, de-interlacing, and brightness/contrast adjustment. VIU2 connects directly to camera sensors and feeds processed video to the graphics pipeline or memory via eDMA. This feature is explicitly documented in Sections 1.3 and 1.4.6 of the MPC5645S datasheet Rev. 14.

How many stepper motors can the SPC5645SF1VLT drive, and what protection features are included?

The SPC5645SF1VLT includes a Stepper Motor Controller (SMC) capable of driving up to six stepper motors in full dual H-bridge configuration. It provides integrated stall detection (SSD), return-to-zero calibration, and short-circuit protection-enabling direct gauge actuation without external driver ICs. This specification is confirmed in Table 1 (MPC5645S device comparison) and Section 1.3 of the MPC5645S datasheet Rev. 14.

What low-power modes does the SPC5645SF1VLT support, and what is the wake-up latency from STANDBY mode?

The SPC5645SF1VLT supports STANDBY, STOP, and HALT low-power modes. From STANDBY mode, wake-up latency is 200–350 µs depending on configuration-enabled by rapid VREG startup (<350 µs) and optional 16 MHz internal RC oscillator activation. In STANDBY, either 8 KB or 64 KB of SRAM is retained, while graphics RAM is lost. These values are specified in Table 2 (Operating mode summary) of the MPC5645S datasheet Rev. 14.

Is the SPC5645SF1VLT pin-compatible with other MPC5645S variants like the 176 LQFP version?

No, the SPC5645SF1VLT is not pin-compatible with 176 LQFP or 208 LQFP variants-it uses the 416-ball TEPBGA package with distinct pin mapping, including dedicated DRAM interface signals and expanded GPIO count (177 pins). Pinouts for each package are separately defined in Sections 2.1–2.3 of the MPC5645S datasheet Rev. 14, confirming no mechanical or electrical interchangeability across packages.
