S3F8S39規(guī)格書(shū)詳情
1.1 S3F8 Series Microcontrollers
Zilog’s S3 Family of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide range of
integrated peripherals, and various mask-programmable Read only memory (ROM) sizes. Address/data bus
architecture and a large number of bit-configurable Input/Output (I/O) ports provide a flexible programming
environment for applications with varied memory and I/O requirements. It includes timer/counters with
selectable operating modes to support real-time operations.
1.2 S3F8S39/S3F8S35 Microcontrollers
The S3F8S39/S3F8S35 single-chip CMOS microcontrollers are fabricated using the highly advanced CMOS
process technology based on Zilog's latest CPU architecture. The S3F8S39/S3F8S35 is a microcontroller with
an embedded 32K/16K byte full-flash ROM.
By using a proven modular design approach, Zilog engineers have successfully developed the
S3F8S39/S3F8S35 by integrating these peripheral modules with the powerful SAM8 RC core:
? Four configurable I/O ports (26 pin)
? Twenty six interrupt sources and eight interrupt levels
? Eight bit-programmable pins for external interrupts
? One watchdog timer function (Basic Timer)
? One 8-bit basic timer for oscillation stabilization
? Two 8-bit timer/counters and three 16-bit timer/counters with selectable operating modes
? A Stop Wake-Up Timer to wake up CPU from Stop Mode
? Watch timer for real time
? Two asynchronous UART modules
? One SPI module
? One IIC module
? Analog to digital converter with 16 input channels and 10-bit resolution
? One BUZ for programmable frequency output

1.3.4 26 I/O Pins
? Twenty six normal I/O pins for 32 pin
1.3.5 Interrupts
? Eight interrupt levels and 26 interrupt sources
? Fast interrupt processing feature
1.3.6 Timers and Timer/Counters
? One programmable 8-bit Basic Timer (BT) for oscillation stabilization control or watchdog timer function.
? One 8-bit timer/counter (Timer A) with three operating modes:
? Interval Mode
? Capture Mode
? PWM Mode
