PIC18F87K90 FAMILY

The PIC18F87K90 family devices that you have

received conform functionally to the current Device Data

Sheet (DS39957D), except for the anomalies described

in this document.

The silicon issues discussed in the following pages are

for silicon revisions with the Device and Revision IDs

listed in Table 1. The silicon issues are summarized in

Table 2.

The errata described in this document will be addressed

in future revisions of the PIC18F87K90 family silicon.

Data Sheet clarifications and corrections start on page 9,

following the discussion of silicon issues.

The silicon revision level can be identified using the

current version of MPLAB

IDE and Microchip’s

programmers, debuggers, and emulation tools, which

are available at the Microchip corporate web site

(www.microchip.com).

For example, to identify the silicon revision level

using MPLAB IDE in conjunction with a hardware

debugger:

1. Using the appropriate interface, connect the

device to the hardware debugger.

2. Open an MPLAB IDE project.

3. Configure the MPLAB IDE project for the

appropriate device and hardware debugger.

4. Based on the version of MPLAB IDE you are

using, do one of the following:

a) For MPLAB IDE 8, select Programmer >

Reconnect.

b) For MPLAB X IDE, select Window >

Dashboard and click the Refresh Debug

Tool Status icon ( ).

5. Depending on the development tool used, the

part number and Device Revision ID value

appear in the Output window.

The DEVREV values for the various PIC18F87K90

silicon revisions are shown in Table 1.

Note: This document summarizes all silicon

errata issues from all revisions of silicon,

previous as well as current. Only the

issues indicated in the last column of

Table 2 apply to the current silicon revision

(B3, C3).

Note: If you are unable to extract the silicon

revision level, please contact your local

Microchip sales office for assistance.

PIC18F87K90 FAMILY PIC18F87K90 Family Silicon Errata and Data Sheet Clarification The PIC18F87K90 family devices that you have received conform functionally to the current Device Data Sheet (DS39957D), except for the anomalies described in this document. For example, to identify the silicon revision level using MPLAB IDE in conjunction with a hardware debugger: 1. The silicon issues discussed in the following pages are for silicon revisions with the Device and Revision IDs listed in Table 1.

PIC18F87K90 FAMILY Silicon Errata Issues Note: This document summarizes all silicon errata issues from all revisions of silicon, previous as well as current. Only the issues indicated by the shaded column in the following tables apply to the current silicon revision (B3, C3). 1. Module: Analog-to-Digital Converter (A/D) 1.1 The A/D will meet the Microchip standard A/D specification when used as a 10-bit A/D.

PIC18F87K90 FAMILY 2. Module: Ports 5. Module: EUSART The input leakage will not match the D060 specification in the data sheet. The leakage will meet the 200 nA specification at TA = 25°C. At TA = 85°C, the leakage will be up to a maximum of 2 A. In Synchronous Transmit mode, data may be corrupted if using the TXxIF bit to determine when to load the TXREGx register. One or more of the intended transmit messages may be incorrect. Work around Work around None.

PIC18F87K90 FAMILY 6. Module: IPD and IDD The IPD and IDD limits will not match the data sheet. The values in bold in Section 31.2 “DC Characteristics: Power-Down and Supply Current PIC18F87K90 Family (Industrial)” reflect the updated silicon maximum limits. 31.2 DC Characteristics: Power-Down and Supply Current PIC18F87K90 Family (Industrial) PIC18F87K90 Family (Industrial) Param.

PIC18F87K90 FAMILY 8. Module: Resets (BOR) Work around None. An unexpected Reset may occur if the Brown-out Reset module (BOR) is disabled, and then re-enabled, when the High/Low-Voltage Detection module (HLVD) is not enabled (HLVDCON<4> = 0). This issue affects BOR modes: BOREN<1:0> = 10 and BOREN<1:0> = 01. In both of these modes, if the BOR module is re-enabled while the device is active, unexpected Resets may be generated. Affected Silicon Revisions A1 B1 B3 C1 C3 X 7.

PIC18F87K90 FAMILY 9. Module: RG5 Pin 10. Module: Primary Oscillator (XT Mode) RG5 will cause excess pin leakage whenever it is driven low. When RG5 is held at 0V, the pin will typically source an additional 160 µA of current. On some parts, using the XT oscillator at the top end of its specified frequency range (3.0 4.0 MHz) may cause the part to cease driving the oscillator.
