1.3 Development tools
1.3.1 Compiler
We do not provide the compiler. Please contact the third parties.
The core of MC96F8204 is Mentor 8051. And, device ROM size is smaller than 64k bytes. Developer can use all kinds
of third party’s standard 8051 compiler.
1.3.2 OCD(On-chip debugger) emulator and debugger
The OCD (On Chip Debug) emulator supports ABOV Semiconductor’s 8051 series MCU emulation.
The OCD interface uses two-wire interfacing between PC and MCU which is attached to user’s system. The OCD can
read or change the value of MCU internal memory and I/O peripherals. And the OCD also controls MCU internal
debugging logic, it means OCD controls emulation, step run, monitoring, etc.
The OCD Debugger program works on Microsoft-Windows NT, 2000, XP, Vista (32bit) operating system.
If you want to see more details, please refer to OCD debugger manual. You can download debugger S/W and manual
from our web-site(http://www.abov.co.kr).
Connection:
−DSCL(MC96F8204 P01 port)
−DSDA(MC96F8204 P00 port)

OCD emulator:
It can write code to MCU device too, because OCD debugger supports ISP (In System Programming).It does not
require additional H/W, except developer’s target system.
Gang programmer: E-GANG4 and E-GANG6
- It can run PC controlled mode.
- It can run standalone without PC control too.
- USB interface is supported.
- Easy to connect to the handler.

1.4 MTP programming
1.4.1 Overview
The program memory of MC96F8204 is MTP Type. This flash is accessed by serial data format. There are four
pins(DSCL, DSDA, VDD, VSS) for programming/reading the flash.
Table 1.2 Descriptions of pins which are used to programming/reading the Flash
1.4.2 On-Board programming
The MC96F8204 needs only four signal lines including VDD and VSS pins for programming FLASH with serial
protocol. Therefore the on-board programming is possible if the programming signal lines are considered when the
PCB of application board is designed.

1.4.3 Circuit Design Guide
At the FLASH programming, the programming tool needs 4 signal lines that are DSCL, DSDA, VDD, and VSS. When
you design the PCB circuits, you should consider the usage of these signal lines for the on-board programming.
Please be careful to design the related circuit of these signal pins because rising/falling timing of DSCL and DSDA is
very important for proper programming.

R2 (2kΩ~ 5kΩ)

VSS
E-PGM+, E-GANG4/E-GANG6
NOTE) 1. In on-board programming mode, very high-speed signal will be provided to pin DSCL and DSDA.
And it will cause some damages to the application circuits connected to DSCL or DSDA port if the
application circuit is designed as high speed response such as relay control circuit. If possible, the
I/O configuration of DSDA, DSCL pins had better be set to input mode.
2. The value of R1 and R2 is recommended value. It varies with circuit of system.
