PIC16F73/74/76/77 PIC16F73/74/76/77 (Rev. C0 Silicon) Data Sheet Errata Clarifications/Corrections to the Data Sheet: The PIC16F73/74/76/77 parts you have received conform functionally to the Device Data Sheet (DS30325B), except for the anomalies described below. In the Device Data Sheet (DS30325B), the following clarifications and corrections should be noted. None. Date Codes that pertain to Rev. C0 Silicon: PIC16F73/74 PIC16F76/77 1. Module: Core 0220 and later 0304 and later The typical and maximum supply currents (parameter D010A) specified for extended voltage devices have been changed. The IDD specifications differ from the Device Data Sheet only for devices operating at a VDD of 3.0V and a FOSC of 32 kHz with the WDT disabled. The changes in the specification are shown in bold in Table 1. TABLE 1: Param Sym.

Module: Pinout Correction The PIC16F73/74/76/77 device family does not offer low-voltage programming. The Device Data Sheet incorrectly lists RB3 as providing the PGM function required for low-voltage programming. References to the PGM function in Tables 1-2 and Table 1-3 of the Device Data Sheet have been removed.

Section 17.1 ("Package Marking Information") is amended to include a marking template and example for 44-pin QFN devices. These are shown in Figure 2. 4. Section 17.2 ("Package Details") is amended to include the mechanical drawing of the 44-pin QFN package, following the existing drawings. This is shown in Figure 3. 5. In the "PIC16F7X Product Identification System" (page 171), the "ML" line item in the "Package" options section should now read (change in bold): PIC16F74 and PIC16F77 devices are now offered in a 44-pin, micro lead frame package (commonly known as "QFN"). This provides near chip scale package size. This option is in addition to the 28-pin QFN packages already available for the PIC16F73 and PIC16F76 devices. The 44-pin QFN package has been added to the product line since the original publication of the Device Data Sheet. The addition of this option requires the following additions to the Device Data Sheet (DS30325B). Referenced figures and tables follow this text. ML = For the sake of completeness, it is also noted that the package designation "MLF" is now replaced by "QFN" in all occurrences throughout the Device Data Sheet. "MLF" should be considered an obsoleted term. 1. The "Pin Diagrams" on pages 2-3 of the Data Sheet are amended with the addition of the 44-pin QFN pinout shown in Figure 1. 2. Table 1.3 of Section 1.0 ("Device Overview") is replaced with an updated version which adds a column for QFN pin assignments. All new information is indicated in bold.
