NXP Semiconductors SPC5123YVY400B

Overview

SPC5123YVY400B from NXP Semiconductors (formerly Freescale) is an automotive-qualified Power Architecture® e300-based microcontroller integrating DDR1/DDR2/LPDDR memory controller, 4× CAN 2.0B interfaces, PCI v2.3, SATA PHY, USB 2.0 OTG with integrated PHY, and 12× programmable serial controllers. It operates at 400 MHz with –40 °C to +85 °C industrial temperature range and is packaged in 516-ball TEPBGA (27 mm × 27 mm).

For engineers reviewing the SPC5123YVY400B datasheet, SPC5123YVY400B pinout, SPC5123YVY400B application, or SPC5123YVY400B equivalent, key selection considerations include AEC-Q100 qualification, dual-domain power management (VDD_CORE/VDD_IO), DDR2 interface timing compliance, PCI bus arbitration logic, and CAN message filtering capability per channel.

Technical Context

The SPC5123YVY400B implements a 32-bit e300 core derived from Power Architecture v2.03, supporting Book E instruction set and Harvard cache architecture (32 KB I-cache / 32 KB D-cache). Its AXE auxiliary execution engine offloads real-time signal processing tasks independent of the main CPU pipeline.

System-level integration includes a 200 MHz 64-bit CSB bus, 83 MHz IP bus for peripherals, and dedicated clock domains for DDR, SATA, USB, and RTC subsystems - each with independent PLLs and voltage regulators (e.g., SATA_VDDA_1P2, USB_VDDA, CORE_PLL_AVDD).

Key Specifications

Pinout & Package

SPC5123YVY400B uses a 516-ball TEPBGA package (27 mm × 27 mm, 1.0 mm pitch) with 12 distinct power/ground domains including VDD_CORE (32 pins), VDD_IO (42 pins), VDD_MEM_IO (13 pins), and dedicated analog supplies (SYS_PLL_AVDD, SATA_VDDA_1P2, USB_VDDA).

FAQ

What is the maximum DDR2 data rate supported by the SPC5123YVY400B?

The SPC5123YVY400B supports DDR2-400 operation (200 MHz clock, 400 MT/s data rate) with programmable drive strength, on-die termination control via MVTT references, and full compliance to JEDEC DDR2 SDRAM specifications. Its DDR interface includes 67 pins (32 DQ, 13 DM/DQS, 12 address/control) and supports 4-bank x 1M x 16 organization configurations.

Does the SPC5123YVY400B include an integrated SATA physical layer?

Yes, the SPC5123YVY400B integrates a fully compliant SATA PHY supporting both SATA I (1.5 Gbps) and SATA II (3.0 Gbps) signaling. It provides dedicated analog pins (SATA_XTALI/O, TXP/TXN, RXP/RXN), voltage domains (SATA_VDDA_1P2, SATA_VDDA_3P3), and calibration reference (SATA_RESREF) - eliminating need for external SATA transceivers.

How many CAN interfaces does the SPC5123YVY400B provide, and what protocol versions are supported?

The SPC5123YVY400B provides four independent CAN 2.0B controllers (CAN1–CAN4), each compliant with ISO 11898-1 and supporting bit rates up to 1 Mbps. All channels feature message object buffers, acceptance filtering, and loopback self-test modes - essential for automotive domain controllers requiring redundant communication paths.

Is the SPC5123YVY400B pin-compatible with the MPC5123YVY400B?

Yes, the SPC5123YVY400B is pin-compatible and register-compatible with the MPC5123YVY400B. Both share identical 516-ball TEPBGA mechanical layout, signal mapping, and memory-mapped peripheral register definitions. The primary distinction is AEC-Q100 qualification and enhanced screening for the SPC5123YVY400B variant.

What power management modes are available on the SPC5123YVY400B?

The SPC5123YVY400B supports five low-power states: doze (core clock gated), nap (peripheral clocks gated), sleep (PLL disabled), deep sleep (core powered down, SRAM retained), and hibernate (VBAT_RTC only active, RTC and GPIO wakeup sources enabled). These modes are controlled via system control registers and require specific entry/exit sequences defined in the reference manual.
