Module: Electrical Specifications In Section 28.0 “Electrical Characteristics”, Table 28-13 (External Clock Timing Requirements) has been replaced with Table 4 below: TABLE 4: EXTERNAL CLOCK TIMING REQUIREMENTS AC CHARACTERISTICS Standard Operating Conditions: 2.50 to 3.6V (unless otherwise stated) Operating temperature -40°C TA +85°C for Industrial -40°C TA +125°C for Extended Param No. Sym Characteristic Min Typ(1) Max Units Conditions OS10 FOSC External CLKI Frequency (External clocks allowed only in EC mode) DC 4 DC 4 — — — — 32 8 24 6 MHz MHz MHz MHz EC, -40°C TA +85°C ECPLL, -40°C TA +85°C EC, -40°C TA +125°C ECPLL, -40°C TA +125°C Oscillator Frequency 3 3 10 31 3 10 — — — — — — 10 8 32 33 6 24 MHz MHz MHz kHz MHz MHz XT XTPLL, -40°C TA +85°C HS, -40°C TA +85°C SOSC XTPLL, -40°C TA +125°C HS, -40°C TA +125°C OS20 TOSC TOSC = 1/FOSC — — — — See Parameter OS10 for FOSC value OS25 TCY Instruction Cycle Time(2) 62.5 — DC ns OS30 TosL, TosH External Clock in (OSCI) High or Low Time 0.45 x TOSC —— ns EC OS31 TosR, TosF External Clock in (OSCI) Rise or Fall Time — — 20 ns EC OS40 TckR CLKO Rise Time(3) — 6 10 ns OS41 TckF CLKO Fall Time(3) — 6 10 ns Note 1: Data in “Typ” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only and are not tested. 2: Instruction cycle period (TCY) equals two times the input oscillator time base period. 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 OSCI/CLKI pin. When an external clock input is used, the “Max.” cycle time limit is “DC” (no clock) for all devices. 3: Measurements are taken in EC mode. The CLKO signal is measured on the OSCO pin. CLKO is low for the Q1-Q2 period (1/2 TCY) and high for the Q3-Q4 period (1/2 TCY). |
