Sharp IC part numbers

Most custom Sharp ICs commissioned by Nintendo usually have their external name on the chips themselves, but they are known to have typical Sharp IC part numbers too.

Nintendo handheld SoCs

These ICs have Sharp part numbers starting with LR359.

Starting from the Nintendo DSi (the first handheld with separate development and production SoCs), development SoCs have the Sharp IC part number (suffixed with the development bonding option / SCFG_OP register value) on the chip.

Confirmed	External name	Sharp IC part number	Product	Notes
Yes	DMG-CPU	LR35902	Game Boy	Sharp IC part number is on the chip with the external name; thus, the most well known of this type . The Game Boy's processor architecture (SM83) was mislabeled as "LR35902" for years (and is still a somewhat-common mislabel to this day).
Yes	CPU MGB	LR35911	Game Boy Pocket	A Korean government source specifies "CPU MGB (LR35911)".
No	CPU CGB	LR3592x	Game Boy Color	Mentioned by a Korean government source and a USA government source. The USA government source gives a "first commercialised date" of 1998-07-06 implying this is for the Game Boy Color, but this is not 100% confirmed.
No	CPU CGB E	LR35926	Game Boy Color	Mentioned by a Korean government source and a USA government source. The part number implies this is a later revision LR3592x. The USA government source gives a "first commercialised date" of 2000-09-11. CPU CGB E is the final SoC revision with WRAM integrated into the main SoC, and is known to have appeared in systems manufactured at the end of 2000 and later.
Unknown		LR3593x		Mentioned by a USA government source, which gives a "first commercialised date" of 1999-07-23. It is completely unknown what this could be; one possible guess is the CPU SGB2 (Super Game Boy 2), but it was never released in the United States.
Undocumented		LR3594x		Not mentioned in any source at all. May have been skipped due to tetraphobia.
Yes	CPU AGB	LR3595x	Game Boy Advance	Mentioned by a Korean government source and a USA government source. The Korean government source specifies that this is a "32-bit RISC CPU and 8-bit CISC CPU", which describes the GBA. Additionally, a later revision (LR35955) is confirmed via other sources.
Yes	CPU AGB B	LR35955	Game Boy Advance SP	Mentioned by a USA government source, which gives a "first commercialised date" of 2001-10-31. Additionally, gba\doc\nintendo\hw\answerfromsharp.doc from the leaked NetCard repository, a document implied to be an English translation of a message from Sharp, specifies "LR35955 (AGS 180nm)".
No	CPU AGB E	LR35960Y	Game Boy Micro	Mentioned by a Japanese government source and a USA government source. The USA government source gives a "first commercialised date" of 2004-04-13. The Japanese government source specifies that this is a "CMOS single chip microcomputer (32 bit RISC + 8 bit CISC)", which describes the GBA.
Yes	CPU NTR	LR35971	Nintendo DS	Mentioned by a Japanese government source and a USA government source. The USA government source gives a "first commercialised date" of 2004-05-31. The Japanese government source specifies that this is a "CMOS 1-chip microcontroller (equipped with ARM9 and ARM7)", which describes the DS. Additionally, gba\doc\nintendo\hw\answerfromsharp.doc from the leaked NetCard repository, a document implied to be an English translation of a message from Sharp, specifies "LR35971 (NTR 130nm)".
No	CPU NTR B	LR35981	Nintendo DS Lite	Mentioned by a Japanese government source and a USA government source. The USA government source gives a "first commercialised date" of 2005-06-28. The Japanese government source specifies that this is a "CMOS 1-chip microcontroller (equipped with ARM9 and ARM7 cores)", which describes the DS.
Undocumented		LR3599x		Not mentioned in any source at all.
Yes	CPU TWL CPU TWL A	LR359A1 LR359A2	Nintendo DSi	DSi development hardware SoCs are labeled "LR359Ax2". Mentioned by a Japanese government source and a USA government source. The USA government source gives a "first commercialised date" of 2007-09-25. The Japanese government source specifies that this is a "CMOS 1-chip microcontroller (equipped with two CPUs, ARM9 and ARM7, and TeakDSP core)", which describes the DSi.
Yes	CPU CTR CPU CTR A CPU CTR B CPU CTR C	LR359B1 LR359B2 LR359B3 LR359B4	Nintendo 3DS	3DS development hardware SoCs are labeled "LR359Bx2". Mentioned by a Japanese government source and a USA government source. The USA government source gives a "first commercialised date" of 2010-05-26. (2011-06-29 for LR359B2, 2011-12-16 for LR359B3, 2013-01-23 for LR359B4) The Japanese government source specifies that this is a "CMOS 1-chip microcontroller (equipped with ARM processor core and TeakDSP core)".
Undocumented		LR359Cx		Not mentioned in any source at all. Could be related to LGR1 (New Nintendo 3DS prototype SoC with only 2 cores) or TNT (INDY).
Yes	CPU LGR	LR359D1	New Nintendo 3DS	New3DS development hardware SoCs are labeled "LR359D12".

Nintendo security microcontrollers (PIF/CIC)

These ICs have Sharp part numbers starting with LR350.

Confirmed	External name	Sharp IC part number	Product	Notes
Yes	PIF-NUS	LR350J04	Nintendo 64	Mentioned by a Korean government source and a USA government source. The Korean government source specifies "PIF-NUS (LR350J04)". The USA government source lists "LR350J" with a "first commercialised date" of 1995-02-23.
Yes	CIC-NUS-6102	LR350G06	Nintendo 64	Mentioned by a Korean government source and a USA government source. The Korean government source specifies "CIC-NUS-6102 (LR350G06) The USA government source lists "LR350G" with a "first commercialised date" of 1995-02-20.
No		LR350R		Mentioned by a USA government source, with a "first commercialised date" of 1998-12-16. Most likely a later revision of CIC-NUS, perhaps CIC-NUS-6103 or CIC-NUS-6105 based on the date.
