UPD78910xA单片机功能分析与IC解密
Opearting voltage:
VDD = 1.8 to 5.5 V (?PD78910xA, 78910xA(A)) VDD = 4.5 to 5.5 V (?PD78910xA(A1), 78910xA(A2)) Max. frequency: 10 MHz
ROM capacities: 2 KB to 4 KB mask ROM
RAM capacities: 256 bytes
30-pin plastic SSOP package
System clock: Crystal/ceramic oscillation
Minimum instruction execution times switchable between high speed (0.2 ?s) and low speed (0.8 ?s) (system clock: 10.0 MHz)
I/O ports: 20
Serial interface: 1 channel
3-wire serial I/O mode/UART mode selectable 8-bit resolution A/D converter: 4 channels
Timers: 3 channels
16-bit timer: 1 channel 8-bit timer/event counter: 1 channel Watchdog timer: 1 channel Multiplier: 8 bits x 8 bits = 16 bits
Vectored interrupt sources: 10
Operating ambient temperature
TA = -40 to + 85°C (?PD78910xA, 78910xA(A)) TA = -40 to +110°C (?PD78910xA(A1)) TA = -40 to +125°C (?PD78910xA(A2))
VDD = 1.8 to 5.5 V (?PD78910xA, 78910xA(A)) VDD = 4.5 to 5.5 V (?PD78910xA(A1), 78910xA(A2)) Max. frequency: 10 MHz
