PIC18F2585/2680/4585/4680 PIC18F2585/2680/4585/4680 Rev. B1 Silicon Errata The PIC18F2585/2680/4585/4680 Rev. B1 parts you have received conform functionally to the Device Data Sheet (DS39625C), except for the anomalies described below. Any Data Sheet Clarification issues related to the PIC18F2585/2680/4585/4680 will be reported in a separate Data Sheet errata. Please check the Microchip web site for any existing issues. The following silicon errata apply only to PIC18F2585/2680/4585/4680 devices with these Device/Revision IDs: Part Number Device ID Revision ID PIC18F2585 0000 1110 111 0 0111 PIC18F2680 0000 1110 110 0 0111 PIC18F4585 0000 1110 101 0 0111 PIC18F4680 0000 1110 100 0 0111 The Device IDs (DEVID1 and DEVID2) are located at addresses 3FFFFEh:3FFFFFh in the device's configuration space. They are shown in binary in the format "DEVID2 DEVID1". All of the issues listed here will be addressed in future revisions of the PIC18F2585/2680/4585/4680 silicon. (c) 2008 Microchip Technology Inc. 1. Module: Master Synchronous Serial Port (MSSP) The MSSP module when configured for I2CTM slave reception, in extremely rare cases, the data received may not be correct. This occurs only if the Serial Receive/Transmit Buffer Register (SSPBUF) is not read within a window after the SSPIF interrupt (PIR1<3>) has occurred. Work around The issue can be resolved in either of these ways: * Prior to the I2C slave reception, enable the clock stretching feature. This is done by (SSPCON2<0>). setting the SEN bit * Each time the SSPIF is set, read the SSPBUF before the first rising clock edge of the next byte being received. Date Codes that pertain to this issue: All engineering and production devices.

DS80414A-page 2 (c) 2008 Microchip Technology Inc. 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.
