9.4 MPU
The Belinea 101570 is controlled by a ?-controlled SM5964.
9.4.1 Description of SM5964
The SM5964 series product is an 8 - bit single chip microcontroller with 64KB flash & 1K byte RAM embedded.
It has In-System Programming (ISP) function and is a derivative of the 8052 microcontroller family. It has 5-
channel SPWM build-in. User can access on-chip expanded RAM with easier and faster way by its ?bank
mapping direct addressing mode? scheme. With its hardware features and powerful instruction set, it?s straight
forward to make it a versatile and cost effective controller for those applications which demand up to 32 I/O
pins for PDIP package or up to 36 I/O pins for PLCC/QFP package, or applications which need up to 64K byte
flash memory either for program or for data or mixed.
To program the on-chip flash memory, a commercial writer is available to do it in parallel programming method.
The on-chip flash memory can be programmed in either parallel or serial interface with its ISP feature.
