NXP Semiconductors KMPC8560VT833LC

Overview

KMPC8560VT833LC from NXP (formerly Freescale) is a PowerQUICC III integrated communications processor featuring an e500v2 32-bit Power Architecture core, 256 KB on-chip L2 cache/SRAM, dual 10/100/1000 Mbps Ethernet controllers (TSEC), DDR-1 SDRAM controller (64-bit, up to 333 MHz data rate), and integrated RapidIO (8-bit, 500 MHz DDR), PCI/PCI-X (64-bit, up to 133 MHz), and CPM subsystems - deployed in carrier-grade wireless baseband units, enterprise routers, and telecom line cards.

For engineers reviewing the KMPC8560VT833LC datasheet, KMPC8560VT833LC pinout, KMPC8560VT833LC application, or KMPC8560VT833LC equivalent, key selection considerations include its 833 MHz core frequency, 1.2 V core supply with 2.5 V/3.3 V I/O domains, 783-pin FC-PBGA package, support for ECC on DDR and L2 memory, and hardware-accelerated communication protocols including HDLC, ATM/UTOPIA, and IEEE 802.3z/ab.

Technical Context

The KMPC8560VT833LC implements a dual-bus architecture: a high-speed Core Complex Bus (CCB) interconnecting the e500 core, L1 caches (32 KB I-cache + 32 KB D-cache with parity), MMU, and 256 KB configurable L2 cache/SRAM; and a peripheral bus domain managed by the Communications Processor Module (CPM) running at up to 333 MHz, handling serial protocols (FCC/SCC/MCC), I²C, SPI, and local bus control. The CPM communicates with the e500 core via 32 KB dual-port RAM and virtual DMA channels.

Its clocking system uses a platform PLL to derive SYSCLK (up to 166 MHz), CCB clock (833 MHz), and core clock (833 MHz) from a single input reference; DDR timing is programmable for 2.5 V SSTL2-compliant interfaces; and RapidIO employs LVDS signaling with source-synchronous DDR timing at 500 MHz data rate. All major I/O domains (GVDD, LVDD, OVDD) are independently powered and sequenced.

Key Specifications

Pinout & Package

KMPC8560VT833LC is housed in a 783-pin FC-PBGA package (27 mm × 27 mm, 1.0 mm ball pitch) with thermal lid and exposed thermal pad. Pin assignments follow Freescale MPC8560EC Rev. 4.2 documentation, with dedicated power/ground banks per I/O domain (GVDD/LVDD/OVDD), differential clock inputs (SYSCLK, EC_GTX_CLK125, RIO_TX_CLK_IN), and function-grouped signal balls (e.g., DDR_A[14:0], DDR_DQ[63:0], TSEC0_TXD[7:0]).

FAQ

What is the maximum DDR-1 SDRAM data rate supported by KMPC8560VT833LC?

KMPC8560VT833LC supports a maximum DDR-1 SDRAM data rate of 333 MHz (166 MHz clock, double-data-rate), delivering 5.3 GB/s peak bandwidth across its 64-bit interface. This is confirmed in Section 4 of the MPC8560 Hardware Specifications Rev. 4.2, which specifies programmable timing for DDR-1 with full ECC and page-mode support up to 16 open pages. The interface is 2.5 V SSTL2-compliant and requires MVREF = GVDD/2.

Does KMPC8560VT833LC include hardware support for Ethernet jumbo frames?

Yes, KMPC8560VT833LC supports 9.6-Kbyte jumbo frames in both TSEC controllers, as documented in Section 1.1 under "Two three-speed (10/100/1Gb) Ethernet controllers." This capability enables efficient transport of large payloads in storage area networks and high-throughput data center interconnects without IP fragmentation.

What power supply sequencing is required for reliable startup of KMPC8560VT833LC?

KMPC8560VT833LC requires strict power sequencing: VDD and AVDD must be applied first, followed by GVDD, LVDD, and OVDD. Per Table 2.1.2 in the Hardware Specifications, rails on earlier steps must reach 90% of target before subsequent rails begin ramping. Violating this sequence risks latch-up or undefined reset behavior, especially if I/O supplies power up before core voltage.

Can KMPC8560VT833LC operate in a purely SRAM-only L2 configuration?

Yes, KMPC8560VT833LC allows the full 256 KB L2 memory to be configured as memory-mapped SRAM - either as a single 256 KB block or two 128 KB blocks - with byte-accessible ECC protected via read-modify-write transactions. This mode is used for deterministic packet buffering where cache coherency overhead is undesirable.

Is KMPC8560VT833LC pin-compatible with other MPC8560 speed grades?

Yes, KMPC8560VT833LC shares identical 783-pin FC-PBGA mechanical and electrical pinout with all MPC8560 variants (e.g., KMPC8560VT667LC, KMPC8560VT1000LC), as confirmed in Section 14 "Package and Pin Listings" of the MPC8560EC Rev. 4.2 specification. Only core frequency, voltage tolerances, and thermal specifications differ between speed grades.
