SCH3223 SCH3223 Silicon Errata and Data Sheet Clarification TABLE 1: SILICON DEV/REV VALUES Device ID(1) Part Number Revision ID for Silicon Revision(2) A SCH3223 Note 1: 2: 7Dh 02h The Device ID is visible as an 8-bit number at Plug and Play Configuration Index 20h. The HW Revision Number is visible as an 8-bit number at Plug and Play Configuration Index 21h and Version/Stepping Number Register 3Fh. TABLE 2: SILICON ISSUE SUMMARY Module Feature Item Number Issue Summary Affected Revisions(1) A none Note 1: none none There are no current silicon issues. If there are multiple revision-letter columns under this one, only those issues indicated in the last column apply to the current silicon revision. 2016 Microchip Technology Inc. DS80000696A-page 1 SCH3223 Data Sheet Clarifications Note: The following typographic corrections and clarifications apply only to the SCH3223 Data Sheet, which is currently Document #00002028B. Other members of the SCH322x family have separate data sheets, and separate errata sheets. TABLE 3: DATA SHEET CLARIFICATION SUMMARY Module Temp Monitor and Fan Control Item Number Issue Summary 1. No Support for HWM SMI Events Power Control 2. 32KHz Clock Required for PB_IN# and PB_OUT# Programmable Clock Output 3. Misleading Label in Figure Temp Monitor and Fan Control 4. Incorrect Values in Table Temp Monitor and Fan Control 5. No Hardware Monitor Interrupt Event on SERIRQ Runtime Registers 6. Inconsistent Default for Runtime Registers LPC Timing Diagrams 7. Inconsistent PCI Clock Max Period Serial Ports 8. References to Non-Existent Serial Port Pins KBC (Non-Existent) 9. References to Non-Existent Keyboard Controller 1. Module: Temperature Monitoring and Fan Control The section “Interrupt as an SMI Event,” is incorrect. Hardware monitoring interrupts are not routed to the SMI block and do not generate SMI events. The section will be removed in its entirety. 2. Module: Power Control Features A clock is required on CLKI32 (pin 99) to clock in and debounce PB_IN# and to assert PB_OUT#. If CLKI32 is either not connected or is not connected to an active clock, PB_OUT# will not be asserted. CLKI32 should be connected to a 32KHz clock. A clock can be provided for PB_IN# by connecting CLKI32 to the SUSCLK output from the core logic south bridge. 3. Module: Programmable Clock Output In the figure “Reset Generation Circuit”, there is a signal labeled “RESETB”. The figure implies that the signal comes in from an input pin. This is incorrect. The figure should indicate that the signal is an internally generated Power On Reset signal. 4. Module: Temperature Monitoring and Fan Control The Nominal Voltage and Maximum Voltage numbers in the table "Voltage Limits vs. Register Setting" are incorrect for the row labeled 2.5V. The table indicates the nominal voltage is 5.0V and the maximum voltage is 6.64V. These two values are incorrect. The correct nominal voltage is 2.5V, matching the signal name. The maximum voltage is 3.32V. 5. Module: Temperature Monitoring and Fan Control In the subsection titled "Interrupt Event on Serial IRQ", in chapter "Temperature Monitoring and Fan Control", it is stated that the interrupt can be routed to the SERIRQ using configuration register 0x70 in Logical Device A. This is not correct. The Hardware Monitor Interrupt cannot be directly routed to a SERIRQ and there is no configuration register 0x70 in Logical Device A. This subsection will be deleted in subsequent releases of the data sheet. As described in the subsections that precede this one, the Hardware Monitor interrupt can be routed onto a pin, onto an SMI or onto a PME. If it is required to route the HWM interrupt to a SERIRQ, it can be routed to an SMI, which can in turn be routed on SERIRQ2. DS80000696A-page 2 2016 Microchip Technology Inc. SCH3223 6. Module: Runtime Registers The default POR values listed in the tables "Runtime Register POR Summary" and "Detailed Runtime Register Description" have some errors and inconsistencies. • The register GP4, at Offset 4E hex, is actually reset to the value 05 hex on VTR POR. Both tables currently give incorrect values for this. Reserved register locations should not be accessed. However, for the sake of interpreting register dumps, there are the following errata regarding initial contents: • The Reserved register at Offset 13 hex is reset to the value 44 hex. The tables are currently inconsistent. • The Reserved register at Offset 10 hex is reset to the value 00 hex, and this happens on every VTR POR (not just on VBAT POR). 7. Module: LPC Timing Diagrams In the chapter “Timing Diagrams”, under “LPC Interface Timing”, the PCI Clock Period is given an incorrect Maximum value of 33.3ns. It should instead be 52.6ns, which represents the lowest guaranteed LPC frequency of 19MHz. 8. Module: References to Non-Existent Serial Port Pins In multiple places there are references to pins belonging to non-existent Serial Ports; for example TXD3, TXD6. These extra UARTs are features of some other SCH322x Family members, but not the SCH3223, and can be ignored. 9. Module: References to Non-Existent Keyboard Controller In the figure “Power Control Block Diagram”, there are references to a “Keyboard Controller”. This is a feature of some other SCH322x Family members, but not the SCH3223, and can be ignored. 2016 Microchip Technology Inc.

DS80000696A-page 5 SCH3223 Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
