PIC16F877

Здравейте.Някой може ли да ми обясни какво значат означенията след PIC16F877 например A-I/L , A-I/PT , 20I/PQ.Предварително ви благодаря.

В DataSheet-a си пише на последните страници:

Device:
PIC16F87XA(1), PIC16F87XAT(2); VDD range 4.0V to 5.5V
PIC16LF87XA(1), PIC16LF87XAT(2); VDD range 2.0V to 5.5V

Temperature Range:
I = -40°C to +85°C (Industrial)

Package:
ML = QFN (Metal Lead Frame)
PT = TQFP (Thin Quad Flatpack)
SO = SOIC
SP = Skinny Plastic DIP
P = PDIP
L = PLCC
S = SSOP


Examples:
a) PIC16F873A-I/P 301 = Industrial temp., PDIP
package, normal VDD limits, QTP pattern #301.

b) PIC16LF876A-I/SO = Industrial temp., SOIC
package, Extended VDD limits.

c) PIC16F877A-I/P = Industrial temp., PDIP package,
10 MHz, normal VDD limits.

Note:
1: F = CMOS Flash
LF = Low-Power CMOS Flash

2: T = in tape and reel - SOIC, PLCC,
TQFP packages only
