Our SX-TIPS in-circuit programmer works well with all SX48/52, include early samples and current silicon revision "A", according to published specifications. It support now new SX18/28 "A" revision. It also draws less than 5 mA from target circuit and have build-in 5-to-12V DC/DC converter. Current software for WIN95/98/NT, DOS version will be also published soon.
