Introduction In this document, Section 2 lists the known functional errata for revision C of PM7380 FREEDM-32P672 and Section 3 lists errors found in Issue 5 of the FREEDM-32P672 datasheet (PMC-1990262). 1.1. Device Identification The information contained in Section 2 relates to Revision C of PM7380 FREEDM32P672 only. The device revision code is marked at the end of the Wafer Batch Code on the face of the device (as shown in Figure 1.1). PM7380 FREEDM-32P672 Revision C is packaged in a 329-pin Plastic Ball Grid Array (PBGA). Figure 1.1: PM7380 FREEDM-32P672 Branding Format.

FREEDM-32P672 Revision C Functional Deficiency List This section lists the known functional deficiencies for Revision C of FREEDM32P672 (as of the publication date of this document). For each deficiency, the known work-around and the operating constraints, with and without the work-around, are also described. Please report any functional deficiencies not covered in this document to PMC-Sierra. PMC-SIERRA, INC. 2 DATASHEET ERRATA PM7380 FREEDM-32P672 PMC-2000951 ISSUE 3 FREEDM-32P672 REVISION C DEVICE ERRATA 2.1. FREEDM may not generate PCI disconnect if host attempts a read multiple command which reads beyond register address 0xFFF. Description: If a host incorrectly attempts a read multiple command whose address range spans beyond a point 4K bytes from the start of the FREEDM-32P672 register space, the FREEDM-32P672 may not issue a PCI disconnect and the PCI bus may hang. Workarounds: Ensure that the PCI host only accesses valid FREEDM-32P672 register addresses. Performance with workaround: FREEDM-32P672 works correctly. Performance without workaround: PCI bus may hang necessitating a system reset. PMC-SIERRA, INC. 3 DATASHEET ERRATA PM7380 FREEDM-32P672 PMC-2000951 ISSUE 3 FREEDM-32P672 REVISION C DEVICE ERRATA 2.2. FREEDM may under-report number of Transmit FIFO underrun events if two such events occur close together. Description: The FREEDM-32P672 reports underrun events on a per-channel basis to the host by setting bit STATUS[2] when a TDR is returned to the TDR Free Queue. If a packet underflows near the end of the packet and the next packet on the same channel underflows near the start of the packet, it is possible that only one TDR is returned to the TDR Free Queue with STATUS[2] set even though 2 underrun events occurred. Workarounds: None. Performance without workaround: Per channel underrun events can occasionally go unreported.
