For engineers reviewing the KMPC8560CVT667JB datasheet, KMPC8560CVT667JB pinout, KMPC8560CVT667JB application, or KMPC8560CVT667JB equivalent, key selection criteria include its 783-pin FC-PBGA package, 1.2 V core supply with 3.3 V/2.5 V I/O rails, RapidIO 8-bit DDR interface, PCI-X 64-bit 133 MHz support, and boot-from-I2C serial ROM capability.

Technical Context

The KMPC8560CVT667JB implements a Book E–enhanced 32-bit e500 Power Architecture core with 32 KB L1 instruction and 32 KB L1 data caches, MMU optimized for embedded networking, and performance monitor facility. Its CPM subsystem operates at up to 333 MHz and handles HDLC, ATM (via UTOPIA), TDM, and I2C protocols via dedicated FCC, SCC, MCC, and SPI controllers.

System-level integration includes a 64-bit DDR SDRAM controller with ECC, 8-way set-associative 256 KB L2 cache configurable as SRAM/cache hybrid, OCeaN four-port crossbar switch for internal packet routing, and dual TSECs compliant with IEEE 802.3z/ab/ac standards - all coordinated through a programmable interrupt controller compliant with OpenPIC architecture and JTAG-accessible system memory map.

FAQ

What is the maximum DDR-1 SDRAM data rate supported by KMPC8560CVT667JB?

KMPC8560CVT667JB supports DDR-1 SDRAM at up to 333 MHz data rate (667 MT/s), with full ECC protection, four-bank addressing, and programmable timing parameters. This enables sustained memory bandwidth of 5.3 GB/s using a 64-bit interface - sufficient for packet buffering and table lookups in mid-range routing applications. The controller also supports registered DIMMs and auto-refresh during sleep mode.

Does KMPC8560CVT667JB support JTAG boundary scan and debug access?

Yes, KMPC8560CVT667JB implements IEEE Std 1149.1-compliant JTAG boundary scan and provides full system access via its System Access Port (SAP). The TAP controller enables 32-bit register reads/writes, cache-line burst memory accesses, and 4-Kbyte block uploads/downloads - allowing in-circuit debugging, flash programming, and hardware validation without requiring external probes or debug agents.

What I/O voltage levels does KMPC8560CVT667JB require for its TSEC Ethernet interfaces?

KMPC8560CVT667JB requires LVDD at either 2.5 V ±125 mV or 3.3 V ±165 mV for its TSEC Ethernet interfaces, depending on the physical layer interface selected: 2.5 V for GMII/TBI/RGMII/RTBI at 2.5 V operation, and 3.3 V for MII or GMII/TBI at 3.3 V operation. Input voltage must remain within GND to LVDD, and overshoot beyond LVDD+0.3 V is permitted only for ≤20 ms during power sequencing.

How many independent Ethernet MACs does KMPC8560CVT667JB integrate?

KMPC8560CVT667JB integrates two independent three-speed (10/100/1000 Mbps) Ethernet controllers - designated TSEC0 and TSEC1 - each compliant with IEEE 802.3z, 802.3ab, and 802.3ac standards. Both support GMII, MII, TBI, RGMII, and RTBI interfaces, jumbo frames up to 9.6 KB, RMON statistics, and programmable CRC generation/checking - enabling dual-port routing, redundancy, or separate control/data plane segmentation.

What is the function of the OCeaN switch fabric in KMPC8560CVT667JB?

The OCeaN (On-Chip Ethernet and Networking) switch fabric in KMPC8560CVT667JB is a four-port crossbar packet switch that routes traffic between TSEC, RapidIO, PCI-X, and DDR interfaces without CPU intervention. It reorders packets based on priority, bypasses blocked destinations, implements starvation avoidance, and supports payloads up to 256 bytes - enabling deterministic low-latency communication among subsystems in telecom control plane architectures.
