TABLE 13-5: EXTERNAL CLOCK TIMING REQUIREMENTS AC CHARACTERISTICS Standard Operating Conditions (unless otherwise specified) Operating Temperature -40 °C ≤ TA ≤ +85°C (industrial), -40 °C ≤ TA ≤ +125°C (extended) Para No. Sym Characteristic Min Typ(1) Max Units Conditions 1A FOSC External CLKIN Frequency(2) DC — 4 MHz XT Oscillator mode DC — 20 MHz HS/EC Oscillator mode (PIC16F506 only) DC — 200 kHz LP Oscillator mode Oscillator Frequency(2) — — 4 MHz EXTRC Oscillator mode 0.1 — 4 MHz XT Oscillator mode 4 — 20 MHz HS/EC Oscillator mode (PIC16F506 only) — — 200 kHz LP Oscillator mode 1TOSC External CLKIN Period(2) 250 — — ns XT Oscillator mode 50 — — ns HS/EC Oscillator mode (PIC16F506 only) 5— — μs LP Oscillator mode Oscillator Period(2) 250 — — ns EXTRC Oscillator mode 250 — 10,000 ns XT Oscillator mode 50 — 250 ns HS/EC Oscillator mode (PIC16F506 only) 5— — μs LP Oscillator mode 2TCY Instruction Cycle Time 200 4/FOSC —ns 3TosL, TosH Clock in (OSC1) Low or High Time 50* — — ns XT Oscillator 2* — — μs LP Oscillator 10 — — ns HS/EC Oscillator (PIC16F506 only) 4TosR, TosF Clock in (OSC1) Rise or Fall Time — — 25* ns XT Oscillator — — 50* ns LP Oscillator — — 15 ns HS/EC Oscillator (PIC16F506 only) * These parameters are characterized but not tested. Note 1: Data in the Typical (“Typ”) column is at 5V, 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 conditions 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. |
