"Type 2" is used in Safrane 1 (X54) from 1992 till 2000

- It is a sample based system

- Seperate box (Phase 1 and Phase 2 boxes look the same but have different functions and partnumbers)

(PHASE 1 boxes only contain 1 language and PHASE 2 boxes can be coded to all 5 languages)

ASK ME FOR A DUMP OF THE GERMAN PHASE1 ROM if you want to help finding out how the Audio is encoded on the CHIP!

Controls for both Phases :

PHASE 1:

SYP x54 (Phase 1)
Renault Number	Sagem number	Language
7700805300	21550991-7 (early REV.)	French
7700805300	21552951-7	French
7700805301		English
7700805302	21552953-8	German
7700805303		Italian
7700805304	21552955-9	Spanish

(1995) SYP_X54 ALLEMAND (German) SAGEM 21552953-8 / 7700805302 D

Synthesizer IC (DSP) : Texas Instruments [D36007NA] (probably a TMS320C1X)

ROM : NEC D23C4001E (DATASHEET)*

Microcontroller : Texas Instruments JL54 CF34086 (seems UNKNOWN to the Internet!!!)

*The Datasheet shows 3 lines that are "User definable" (active on high or low). On the board CE2 is tied to VSS. OE & CE1 are tied together. My guess is that OE & CE1 are active high... Maybe this info will help me later to read the chip...

Look what i have found... The ROM D23C4001E looks suspiciously like a M27C4001 Rom... Maybe its a simple read with my chip programmer... VPP on the 27C4001 is the 12V programming voltage input. As long as i do not try to write to my ROM it should be safe... The expected input on CE2 of the 23C4001 is +5v during normal operation (as we have seen above from the circuit). If OE and CE1 are configured to work like a normal 27C4001 it should just work to read it... 

Ok. That was too easy. I just desoldered the ROM and put it into my EPROM reader. I used a preset for "NEC UPD27C4001 @ DIP32" and it read just fine... i guess. The Chip is nearly full of data and i have no idea how its encoded. I tried to import it in Audacity with every available setting. I got no results that sounded like a Voice...

Maybe you have an idea? Contact me.

PHASE 2:

(1999) SYP X54-2 SAGEM 21614185-9/3 / 7700847660

Synthesizer IC (DSP) : Texas Instruments TMS320C14 [D34004FN] (DATASHEET) 

ROM : OKI M531602C (DATASHEET)

Its nice that they actually printed the type of DSP on the chip. That gives me a nice clue to what Phase1 is using... The ROM is exactly the same as they used in "TYPE3 (Laguna) Phase 2" (maybe even same content).
