Advanced Information DS40121A-page 13 Enhanced PIC16LV5X 5.4 Timing Diagrams and Specifications FIGURE 5-2: EXTERNAL CLOCK TIMING - PIC16LV5XA TABLE 5-1: EXTERNAL CLOCK TIMING REQUIREMENTS - PIC16LV5XA AC Characteristics Standard Operating Conditions (unless otherwise specified) Operating Temperature 0 °C ≤ TA ≤ +70°C (commercial), –20 °C ≤ TA ≤ +85°C (industrial) Operating Voltage VDD range is described in Section 10.1, Section 10.2 and Section 10.3 of the Enhanced PIC16C5X data sheet (DS30236B). Parameter No. Sym Characteristic Min Typ (1) Max Units Conditions FOSC External CLKIN Frequency (2) DC — 2.0 MHz RC osc mode DC — 2.0 MHz XT osc mode DC — 200 kHz LP osc mode Oscillator Frequency (2) DC — 2.0 MHz RC osc mode 0.1 — 2.0 MHz XT osc mode 5 — 200 kHz LP osc mode 1TOSC External CLKIN Period (2) 500 — — ns RC osc mode 500 — — ns XT osc mode 5.0 — — µs LP osc mode Oscillator Period (2) 500 — — ns RC osc mode 500 — 10,000 ns XT osc mode 5.0 — 200 µs LP osc mode 2TCY Instruction Cycle Time (3) — 4/FOSC —— 3 TosL, TosH Clock in (OSC1) Low or High Time 50* — — ns XT oscillator 2.0* — — µs LP oscillator 4 TosR, TosF Clock in (OSC1) Rise or Fall Time — — 25* ns XT oscillator — — 50* ns LP oscillator * These parameters are characterized but not tested. Note 1: Data in the Typical (“Typ”) column is at 3.8V, 25˚C unless otherwise stated. These parameters are for design guidance only and are not tested. 2: All specified values are based on characterization data for that particular oscillator type under standard operating condi- tions with the device executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or higher than expected current consumption. When an external clock input is used, the “max” cycle time limit is “DC” (no clock) for all devices. 3: Instruction cycle period (TCY) equals four times the input oscillator time base period.
