the following microcontroller families:

• Philips P89C51Rx+ (+12V Vpp)

• Philips P89C51Rx2 (No Vpp required)

• TEMIC T89C51RD2 (No Vpp required)

• Powerful ‘GEMINI’ programmer

interface software:

•• Compatible with Windows 95, 98 and NT

•• Device commands include Check Signature,

Blank Check, Erase, Read, Write, Verify, Security,

Auto-program

•• Powerful buffer system with Blank Check, Erase,

Fill, Goto and Checksum commands

•• Supports reading and writing of target device

fuse bits and lock bits

•• Supports Binary and Intel HEX file formats

•• User-configurable

~ RESET polarity

~ RESET timing state machine

~ Target Baud Rate

•• Context-sensitive help system

• Field upgradable firmware via

Internet downloadable utility -

caters for new programmer

algorithms in the future

• On-board Vpp generator (+12V)

• Programmer ‘Active’ signal - used to

drive an LED on the target system

• Connects to spare PC COM (serial)

port

• Robust ‘EMC-friendly’ design plus

I/O pin protection

• CE compliant product

The GEMINI-1 is a state-of-the-art

development programmer supporting the

new range of In-System Programmable (ISP)

microcontrollers from Philips

Semiconductors and TEMIC

Semiconductors. These microcontrollers

feature serially downloadable memory

allowing the CODE to be updated in-system

without physically removing the target

device from the application board. The

serial programming is via the on-chip UART.

General notes

The Gemini programmer:

• Supports the ISP (In-System Programming)

mode only.

• Automatically writes 00h into the ‘Status

Byte’ and ‘FCh’ into the ‘Boot Vector’ at

the end of every programming operation.

• Does NOT support custom ‘Boot Loaders’

using the ‘IAP’ (In Application Mode)

• Will only operate with a Vcc between

4.8V and 5.8V

• Does NOT support block ERASE or

READ/WRITE of the target microcontroller

FLASH memory.

Please Note:

This programmer is designed for development

use only.
