MCP215X MCP215X Rev. A Silicon/Data Sheet Errata The MCP215X parts you have received conform functionally to the device data sheets (DS21655A and DS21690A), except for the anomalies described below. All of the issues listed here will be addressed in Revision B of the MCP215X silicon. 1. Module: IR Protocol Handler When the Primary Device has initiated IR communication with the MCP215X, and the Primary Device is removed before the MCP215X enters Discovery mode, the MCP215X will lockup. Work around Ensure that communication between the Primary and Secondary IS NOT interrupted during initial communication. If the MCP215X has not indicated a valid link for a given timeframe (as determined by the application), then the MCP215X will need to be reset. 4. Module: IR Protocol Handler The MCP215X does not properly monitor the number of packets received by the Primary. If the number of packets received by the Primary does not match the number sent, the link may shut down. Work around The Primary Device may reestablish a link to the MCP215X (the Secondary Device) as permitted by the application. 5. Module: Test Escapes The test flow for some MCP215X devices was not adhered to. Devices with the following Traceability Codes do not function (will not communicate with the UART port or IR port) and should be replaced. Package Traceability Code PDIP 0145H9K 0215G9B 2. Module: Host UART If the MCP215X does not have a link established in Normal Connect Mode (NCM), overflowing the Host UART buffer will lock up the device. Work around The Host Controller firmware must respect the Host UART CTS Flow Control signal, as is indicated in the data sheet. 3. Module: IR Protocol Handler Note: For Palm(R) PDA applications only If an unexpected command or response from the Palm PDA occurs during the Discovery phase, the MCP215X may lock up. This is due to the Palm Operating System (Palm OS(R)) terminating Discovery when the IrDA(R) Standard Secondary Device transmits an unexpected response to the Palm OS. The MCP215X will lock up when the Primary Device aborts Discovery phase. Work around SOIC 0215G9U SSOP 0210GUQ Work around Contact your Microchip sales representitive to authorize a RMA to exchange these devices. 6. Module: Host UART Note: For the MCP2150 only The state of the DSR pin correctly indicates when the MCP2150 has initialized after a device reset (until an IR link is established), but will continue to track the state of the CD pin after a link has been established. Work around Monitor the DSR pin to determine when the device has completed initialization until a link is established. The DSR pin can then be ignored until the next time the Host Controller resets the MCP2150. The MCP215X will need to be reset if the MCP215X has not indicated a valid link for a given timeframe (as determined by the application). (c) 2006 Microchip Technology Inc. DS80261A-page 1 MCP215X 7. Module: IR Protocol Handler The MCP215X issues two RR packets upon entry into Normal Response Mode (NRM) prior to the Primary Device sending a packet. Enhancements for Rev B Devices: The following device enhancements should be noted for Silicon Rev. B devices (from Silicon Rev. A devices): 1. This does not appear to be a compatibility issue with current IrDA compatible devices. Work around None 2. Clarifications/Corrections to the Data Sheet: In the device data sheets, DS21655A and DS21690A, the following clarifications and corrections should be noted: None. DS80261A-page 2 3. The MCP2150 now has retransmit capability for outgoing IR Packets. This retransmission occurs when the number of "packets" sent does not match the number "packets" received. The MCP215X will attempt to retransmit a "packet" only a limited number of times. The Host UART Receive Buffer window (# of bytes that MCP2150 Host UART can receive before de-asserting CTS) was increased from 40 to 60 bytes. This provides consistency with the MCP2155. Increased the number of initial BOF characters from 1 BOF to 11 BOF for better compatibility with future IrDA Standard devices. (c) 2006 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.
