PIC16(L)F1788/1789 PIC16(L)F1788/1789 Family Silicon Errata and Data Sheet Clarification The PIC16(L)F1788/1789 family devices that you have received conform functionally to the current Device Data Sheet (DS41675A), 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. The silicon issues are summarized in Table 2. 2. 3. The errata described in this document will be addressed in future revisions of the PIC16(L)F1788/1789 silicon. 4. 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 (B1). Data Sheet clarifications and corrections start on page 5, 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). TABLE 1: 5. Using the appropriate interface, connect the device to the hardware debugger. Open an MPLAB IDE project. Configure the MPLAB IDE project for the appropriate device and hardware debugger. 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 ( ). Depending on the development tool used, the part number and Device Revision ID value appear in the Output window. Note: If you are unable to extract the silicon revision level, please contact your local Microchip sales office for assistance. The DEVREV values for the various PIC16(L)F1788/ 1789 silicon revisions are shown in Table 1.

DS80000575B-page 2 2013 Microchip Technology Inc. PIC16(L)F1788/1789 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 (B1). 1. Module: Comparator 2.2 64 MHz Clock When the Configuration bits select both PLL enabled and INTOSC as the default system clock, then the 64 MHz PSMC clock will not operate after a device Reset until the IRCF<3:0> bits of the OSCCON register are set to '111x'. The IRCF bits can then be set to any desired value and the 64 MHz clock will continue to operate. Work around The comparator operation in Low-Power, LowSpeed mode (CxSP = 0) may not perform properly. Ensure that the PLLEN bit of the CONFIG2 register is cleared when the FOSC<2:0> bits of the CONFIG1 register select the INTOSC (FOSC<2:0> = 100). Work around Affected Silicon Revisions 1.1 No Low-Power, No Low-Speed Mode Use the comparator in High-Power mode. Affected Silicon Revisions B0 B1 X X 2. Module: PSMC 2.1 Rising Edge Inhibit B0 B1 X X 3. Module: Resets 3.1 Low-Power Sleep (PIC16F1788/1789 devices only) When the device is in Low-Power Sleep (VREGPM = 1 and SLEEP instruction is executed), a MCLR Reset will be reported as a POR Reset: When the period and falling edge sources are from the same asynchronous input, then a race condition may occur where the period is detected before the falling edge. When this occurs, the falling edge properly terminates the cycle but subsequent rising edge inputs are ignored. Work around Work around Use Normal-Power Sleep mode (VREGPM = 0). To configure the PSMC for fixed off-time and variable frequency, set the following: Affected Silicon Revisions • • • • Period = Asynchronous feedback Rising Event = Synchronous @ PSMCxPH = 0 Falling Event = Synchronous @ PSMCxDC = Off Time Output inverted so drive time is from falling event to period event. Affected Silicon Revisions B0 B1 X X • PD = 1 • POR = 0 • RDMCLR = 1 B0 B1 X X 4. Module: CPU 4.1 BRA/BRW If a BRA or BRW instruction is executed concurrently with an interrupt event, the ISR routine can restore the PC to an incorrect value. Work around Use the GOTO instruction rather than the BRA or BRW instruction. Affected Silicon Revisions B0 B1 X 2013 Microchip Technology Inc. DS80000575B-page 3 PIC16(L)F1788/1789 5.

Work around None. Affected Silicon Revisions B0 B1 X X 6. Module: CCP3 6.1 CCP3 Capture (PIC16(L)F1789 only) When the input threshold control for RE0 is configured for TTL, then the CCP3 capture input is ignored. Work around Use ST threshold.
