| PIC18F2525/2620/4525/4620 PIC18F2525/2620/4525/4620 Data Sheet Errata Clarifications/Corrections to the Data Sheet: In the Device Data Sheet (DS39626B), the following clarifications and corrections should be noted. Any silicon issues related to the PIC18F2525/2620/4525/ 4620 devices will be reported in a separate silicon errata. Please check the Microchip web site for any existing issues. 1. Module: I/O Ports The TRIS setting for the TX pin on PORTC in Table 10-5 of the Device Data Sheet was incorrectly stated as `1'. The correct TRIS setting for the TX pin on PORTC is `0'. 2. Module: Resets The PR2 initialization condition shown in Table 4-4 for MCLR Resets, WDT Reset, RESET Instruction, Stack Resets and Wake-up via WDT or Interrupt should read "uuuu uuuu" as shown in the following table (changes are shown in bold text): TABLE 4-4: Register INITIALIZATION CONDITIONS FOR ALL REGISTERS Applicable Devices Power-on Reset, Brown-out Reset 1111 1111 MCLR Resets, WDT Reset, RESET Instruction, Stack Resets uuuu uuuu Wake-up via WDT or Interrupt uuuu uuuu PR2 2525 2620 4525 4620 Legend: u = unchanged, x = unknown, - = unimplemented bit, read as `0', q = value depends on condition. Shaded cells indicate conditions do not apply for the designated device. 3. Module: Voltage-Frequency Graph The title information for Figure 26-2: VoltageFrequency Graph (Extended), references the wrong device family and has been changed to read as follows: FIGURE 26-2: PIC18F2525/2620/4525/4620 VOLTAGE-FREQUENCY GRAPH (EXTENDED) (c) 2005 Microchip Technology Inc. DS80222B-page 1 PIC18F2525/2620/4525/4620 4. Module: DC Characteristics In Section 26.3 "DC Characteristics" (page 336), the specifications for VIL parameters D033B and D034 have been clarified and now read as follows: 26.3 DC Characteristics: PIC18F2525/2620/4525/4620 (Industrial, Extended) PIC18LF2525/2620/4525/4620 (Industrial) Standard Operating Conditions (unless otherwise stated) Operating temperature -40C TA +85C for industrial Characteristic Input Low Voltage OSC1 T13CKI VSS VSS 0.3 0.3 V V XT, LP modes Min Max Units Conditions DC CHARACTERISTICS Param Symbol No. VIL D033B D034 5. Module: A/D Converter Characteristics In Table 26-24: A/D Converter Characteristics (page 359), specification A40 has been added: TABLE 26-24: A/D CONVERTER CHARACTERISTICS: PIC18FX525/X620 (INDUSTRIAL, EXTENDED) PIC18LFX525/X620 (INDUSTRIAL) Param Symbol No. A40 IAD Characteristic A/D Current from VDD PIC18FXXXX PIC18LFXX20 Min -- -- Typ 180 90 Max -- -- Units A A Conditions Average current during conversion 6. Module: Instruction Set In Table 24-2: PIC18FXXXX Instruction Set (pages 270-271), the ADDWF, ADDWFC and BTG instructions have been modified. The changes are shown in bold text: TABLE 26-25: PIC18FXXXX INSTRUCTION SET Mnemonic, Operands 16-Bit Instruction Word Description Cycles MSb LSb Status Affected Notes BYTE-ORIENTED OPERATIONS ADDWF ADDWFC BTG Note 1: f, d, a f, d, a f, b, a Add WREG and f Add WREG and Carry bit to f Bit Toggle f 1 1 1 0010 0010 01da 00da ffff ffff ffff C, DC, Z, OV, N ffff C, DC, Z, OV, N ffff None 1, 2 1, 2 1, 2 BIT-ORIENTED OPERATIONS 0111 bbba ffff When a Port register is modified as a function of itself (e.g., MOVF PORTB, 1, 0), the value used will be that value present on the pins themselves. For example, if the data latch is `1' for a pin configured as input and is driven low by an external device, the data will be written back with a `0'. If this instruction is executed on the TMR0 register (and where applicable, `d' = 1), the prescaler will be cleared if assigned. 2: DS80222B-page 2 (c) 2005 Microchip Technology Inc. PIC18F2525/2620/4525/4620 7. Module: Timing Diagrams and Specifications Table 26-6: External Clock Timing Requirements (page 343), has been revised (changes and additions are shown in bold text).

All specified values are based on characterization data for that particular oscillator type under standard operating conditions with the device executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or higher than expected current consumption. All devices are tested to operate at "min." values with an external clock applied to the OSC1/CLKI pin. When an external clock input is used, the "max." cycle time limit is "DC" (no clock) for all devices. 8. Module: EUSART The RX pin sampling information in Section 18.1.2 "Sampling" has changed. This section now reads as follows: 9. Module: MSSP In Section 17.3.2 "Operation", the following note has been added: Note: The SSPBUF register cannot be used with read-modify-write instructions, such as BCF, BTFSC, COMF, etc. 18.1.2 SAMPLING The data on the RX pin is sampled three times by a majority detect circuit to determine if a high or a low level is present at the RX pin when SYNC is clear or when BRG16 and BRGH are both not set. The data on the RX pin is sampled once when SYNC is set or when BRGH16 and BRGH are both set. 10. Module: QFN In the QFN pin diagram on page 3 and in Table 1-3: PIC18F4525/4620 Pinout I/O Descriptions, the following note has been added: Note: It is recommended to connect the bottom pad of QFN package parts to VSS.
