48/52-SX

data sheet, press release, and product briefs
The SXKey software (version 1.07 as of 06/17/99) does not support programming or ICE.
A special SXKey52 adapter and SXKey52 software (v1.07 for 48/52) is available from Scenix only (not Parallax) that programs the 52 but does not yet support ICE. A new version with ICE is due end of this month 06/17/99.
Advanced Transdata has a $375 "in-system debugger" pn SX-ISD that is an upscale version of the SXKey system. It is recommended by top Scenix engineers. It fully supports the 48/52 with programming and ICE.
For prototyping, the 52 pin surface mount PQFP package will require an
- a 52pin PQFP (0.65mm pin spacing 13.2mm x 13.2mm tip to tip) to pcb (pn: 160-8404-02) or wirewrap (pn: 160-8404-07) adapter from http://www.adapters.com for about $65 but watch out! the leads on the chip come down about half off the solder pads on the top of the adapter requireing that you manually push all the pins back against the body before soldering. They do not have an adapter with a socket for prices less than $250 each min qty 5.
- a test socket, pn: 7310-052-X-08 from http://www.wellscti.com/ser7000.htm distributed by SouthWest Sales 1-602-424-7327 for about $27.70 but the foot print on the socket is not appropriate for prototyping so the unit would have to be soldered to a (custom) adapter board with leads run out to posts on more standard spaceing (The 7010-052-X-08 part is the MS-026 JDEC foot form (1.0mm lead length) and the sx52 is MS-022 (1.60mm lead length)
- a test socket, pn: FTQ-52-0.65-02A from http://www.enplas.com/prod/qfp.htm distributed by High Performance Test, Inc. 1-510-445-1182 or evann@hastsol.com for about $24.36 but, again, the foot print on the socket is not appropriate for prototyping so the unit would have to be soldered to a (custom) adapter board with leads run out to posts on more standard spaceing so we are back to adapters.com.

Compilers

Pavel Baranov's C2C C-compiler runs on Win-95, DOS and Linux and compiles for PIC and SX (free)
Pavel Baranov's P2C Pascal compiler (free)
JAL a Pascal like compiler produces .hex and MPASM .asm files (free)
Richard Ottosen's LstFix can postprocess listing files from MPASM to remove unnecessary lines and make them easier to read.
Chuck Glenn's Scenix Toolkit includes an assembler and simulator for Windows

Emulators/in-circuit programmers

Parallax SX-Key is a "wonder of magic" (about $150)
Advanced Transdata SX-ISD is a high class (extra features) version of the SX-Key (about $375)

Simulators

Loren Blaney's SxSim, a free screen-oriented simulator for the SX that's very easy to use.
Chuck Glenn's Scenix Toolkit includes an assembler and simulator for Windows
UMPs from VMDesign.com runs under Windows and simulates many processors and external hardware. New devices can be added by writing a DLL in C or pascal. Distributed in the US by wirz.com for $649
