Hello,

FAE from Italy here... A customer using ST92T141 is asking us some information on how to perform an in circuit programming on this OTP microcontroller in such a way to optimize board manufacturing. Which pins are involved? Is there some documentation about it? Best Regards E.C.

Hello

One can do ISP JTAG with ST92E141 EPB, thanks to the W1 connector (cf pin-out here below). Beware that the inputs OSCIN, RESET et VPP, managed by the EPB, must be deconnected when programming; Clearly this is a limitation of this approach (together with the JTAG high pin count). Best regards, VO --- W1 is a 16-pin connector (2.54mm pitch = HE10). TMS 1 - 2 OSCIN TCK 3 - 4 RESETn TDI 5 - 6 TEST0 TRST 7 - 8 NC TDO 9 -10 NC NC 11-12 NC NC 13-14 VPP GND 15-16 GND NC = Not Connected TMS = P5.3 TCK = P5.4 TDI = P5.2 TRST = P5.5 TDO = P5.0 TEST0 = P5.7 [ This message was edited by: vonde on 12-09-2003 10:18 ]
