Renault Speech Synthesizer "TYPE 1" 1983 - 1992

< TO "TYPE 4"  | <HOME> | TO "TYPE 2">

"Type1" is used in R11 and R25 from 1983 till 1992

- This type uses Texas Instruments speech synthesis like a Speak & Spell

- The system is fitted in form of a seperate box.

- Languages : French, English, German, Italian, Spanish

This box went through several very interesting revisions. Each Phase and each Language have own voice ROM´s. On the first versions used in R11 (1983) it talked a lot and spoke detailed informations. The first updated version (1985) of the box was fitted in R25 as "Phase 1". It spoke less detailed informations (probably to get the information to the driver faster). "Phase 2" was introduced at the end of 1988. Phase 2 spoke even less and cut away the TEST function that explained the features in spoken words. TEST was replaced by a simple announcement that all systems are fine (or the faults stored). Phase 2 also got new control buttons.

The boxes are labeled with stickers that can fall off after all the years. That makes it difficult to identify the boxes. You can identify PHASE 2 boxes from its grounding tab on the side of the case wich PHASE 1 does not have. Earlyer versions of PHASE1 used less metal foil around the case. I THINK the earlyest versions of R11 systems used the BARE CIRCUIT BOARDS without a case (wich makes finding them nearly impossible).

For detailed analysis of the hardware follow this >LINK< to my reverse engineering project.

PHASE 2:

The boards shown here are a very early French Phase 2 version. CM62314 is the French Phase2 ROM. TMS5110A above the ROM is the speech synthesizer IC.

This is an early version of the box in a R11 (PHASE 0). It talks A LOT!

Renault Speech Synthesizer "TYPE 2" 1992 - 2000

< TO "TYPE 1"  | <HOME> | TO "TYPE 3">

"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:

(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).

Renault Speech Synthesizer "TYPE 3" 1994 - 2001

< TO "TYPE 2"  | <HOME> | TO "TYPE 4">

"TYPE 3" is used in Renault Laguna 1 (x56) / 1994-2001

- It is a Sample based system

- The speech synthesizer hardware is integrated into the cluster. (Cluster must have green connector [HIGH version])

- Languages: French, English, German, italian, Spanish, Dutch

PHASE 1:

Phase 1 parts have a seperate distance counter display in the center of the cluster. Phase 1 uses a red, a blue and a green connector.

PHASE 2:

Phase 2 parts show the distance counter in the upper borardcomputer display. Phase 2 has a red, a grey and a green connector. Phase 2 uses different connectors. 

Phase 2 speech synthesizer hardware:

ROM : 44PIN OKI M531602C (DATASHEET) (2MB)

FPGA : PIOLOGO3  (Toshiba) TC110G08AF* (DATASHEET)

MICROCONTROLLER : Texas Instruments TMS370C056 (DATASHEET) and D36011FNA (UNKNOWN)

* I´m not sure if "PIOLOGO3" is the speech synthesizer... At least it has direct connections to the voice ROM... Maybe it is a FPGA or something like that. If you search for the number below PIOLOGO3 (TC110G08AF)  you will find some old Harddisks with this chip... I am pretty sure a Harddisk does not have a speech synthesizer...

EDIT: I was right... it is a gate array. TC... sounded a lot like a partnumber from Toshiba. some searches later i found the Toshiba TC110G gate array in the version 08 (TC110G08) with around 3200 usable gates. >DATASHEET<... I have to make some measurements to see wich of the IC´s generates the Voice output that is fed into the amp... 

I finally found a ROM Chip that looks exactly like our MASKROM ... I think its time to order a adapter so that i can try to dump it... M27C160 (DATASHEET) seems to be the regular version of the MSM531602E
