Micro-ISP Series User Manual V2.03 Target System Requirements
following target system requirements must Micro-ISP programmer operate correctly
Target oscillator
target microcontroller oscillator must running between certain prescribed frequencies. These found relevant microcontroller data sheets. oscillator could external crystal/resonator could internal oscillator (e.g AT90S1200 AT90S2343).
Power
Micro-ISP requires regulated supply operate. This supply taken either from user target system external power supply unit (PSU). programmer should operate correctly between specified operating voltage limits (see hardware specifications).
RESET circuit
serial programming mode family devices initiated asserting RESET correct sense certain period time. programmer must, therefore, able assert RESET user target microcontroller. External control RESET implemented number different ways. Family (90S) ATmega ATtiny Reset Polarity Active High Active Active Active
Enable Fuse
Enable Fuse (SPIEN) must ENABLED target microcontroller device programming work. SPIEN fuse only programmed parallel programming mode with device socket. Atmel microcontrollers supplied from factory with SPIEN fuse enabled default.
Micro-ISP Series User Manual V2.03 Atmel AT89S/89LS Notes
RESET circuit
This should `Active HIGH' RESET circuit. 89S/89LS devices suffer from many problem correctly entering `Serial Programming Mode. programmer must output number pulses RESET which synchronise target device. network used (C=10µF, R=10K), default timings parameters `T1.T6' should work correctly. However, RESET `Supervisor Device' used, timings `T1.T6' must altered that pulse train filtered RESET circuit.

MOSI/MISO connections
Atmega microcontrollers differ from other AVR/89S device that programming performed UART pins `PD1/RXD' `PD0/TXD' pins instead MOSI MISO. This connection system lead driver contention problems with `PROG-MOSI' line output driver RS-232 Transceiver chip. Basically, `RS-232-RXD' line asserted, programmer able assert `PROG_MOSI' pin.

Micro-ISP Series User Manual V2.03 Micro-ISP Compatible Target Systems
products listed below have been specially designed interface with Micro-ISP programmer
AVR/89S Socket Stealer Modules
Plugs into most 40-pin generic AVR/89S microcontroller sockets. Ideal AVR/89S evaluation small production runs where target board redesign would more expensive where time constraints have been imposed.
Microcontroller Personality Module
This dedicated Microcontroller Personality module supports most 8-pin, 20-pin 40-pin Atmel 8051 microcontrollers. module features header which connects `Micro-ISP' programmer. plugged into either `Evaluation' module running simple examples into separate `Prototyping' module where developer construct his/her circuitry `real' project.
Micro-ISP Series User Manual V2.03 Troubleshooting Guide
Installation problems
Does your meet minimum requirements this product? have spare serial port? Have connected serial cable from port Micro-ISP? Have selected correct port? serial port already another application?
In-system programming (ISP)
MOSI, MISO, SCK1 RESET connection from target system correctly wired? Does target RESET circuit allow remote control RESET line from Micro-ISP? target system powered correct voltage? target microcontroller enabled (i.e. SPIEN ENABLED)? target oscillator (internal external) running? target frequency correct target oscillator frequency being used? FLASH EEPROM write times correct value target voltage?
AT89S Problems
Symptom: Virgin device programs once then will re-program. (Error message `Can program location 0000h') Workaround: Connect target device ground. (forces microcontroller execute from external memory) Remove code your firmware which writes delay from RESET writing 700ms. Re-program device (should successful)
ATmega problems
time this manual going press, ATmega103 microcontrollers would erase correctly below 3.4V would program reliably below 3.7V. Future revisions silicon should hopefully cure these problems.
AT90S/AT90LS/ATtiny Problems
time this manual going press, ATmega103 microcontrollers would erase correctly below 3.4V. Future revisions silicon should hopefully cure this problem.
