Memory Management
Overview
The F256 series comes with 512KB or 2MB of SRAM, and 512 KB of internal system flash memory. Up to 256 KB additional Memory, either RAM or Flash, can be added through the Expansion Port.
| Model | Hardware CPU | SRAM | Flash | Expansion Port | DRAM |
|---|---|---|---|---|---|
| F256Jr | 65C02 | 512kB (512k×8) | 512kB | 256kB | — |
| F256K | 65C02 | 512kB (512k×8) | 512kB | 256kB | — |
| F256Jr2 | 65816 | 2MB (1M×16) | 512kB | 256kB | — |
| F256K2 | 65816 | 2MB (1M×16) | 512kB | 256kB | 128MB (not yet supported) |
The 1st gen 65c02 systems have an 8-bit data bus and a 16-bit CPU address bus, with an MMU managing 8 × 8k banks to address 512kB RAM plus flash, expansion, and the IO pages.
The 2nd gen 2MB 65816 systems have 16-bit wide SRAMs, enabling higher bandwidth through the FPGA, even though the processor still has an 8-bit wide data bus. The same 64k address MMU with 512kB RAM configuration is used, but the Core2x FPGA core released in the summer of 2025 can enable 24 bit (16 MB) addressing and the full 2MB of SRAM both flat & banked.
A FPGA-based 6809 CPU can be optionally run on all F256 models which will also use this same MMU, and disable the hardware CPU. A 68k FPGA-based processor core is also coming, which should use flat memory addressing only.
NOTE: Changes associated with Core2x will be in italics and underlined throughout this page.

Note that the SRAM pages 1-3 are not contiguous, but aligned to 1MB starting addresses.
Memory Management Unit (MMU)
While the address bus is generally 21 bits wide, the CPU address bus of the 65c02 and the FNX6809 is only 16 bits wide. The 65816 defaults to a 64kB MMU mapped configuration as well, though the Core2x FPGA core enables the flat 24-bit address bus.
The MMU splits the 64kB address space into 8 visible slots of 8kB each. A theoretical max of 256 selectable 8kB banks yields a 2MB address space, which maps 512kB RAM, flash, and expansion. IO pages have their own space of numbered banks that overlay one fixed slot ($C000-$DFFF). The Core2x MMU expands the bank numbers to 10 bits, for 8MB of address space that can encompass the rest of the 2MB RAM.
There are 4 separate sets of MMU configurations called MLUT 0-3 (Memory Lookup Tables), for easy switching between well-known (including kernel vs user) memory mapping states. Each MLUT holds 8 bank selections, one for each 8kB memory slot respectively. IO mapping is optional, independent of MLUT selection, and overrides slot 6 at $C000.
Only one MLUT is active at any one time. To select the active MLUT, the lower two bits of address $0000 (MMU_MEM_CTRL) are used.
Editing of MLUTs is also controlled by MMU_MEM_CTRL ($0000): Bits 4 and 5 determine which MLUT to be edited, independent of which MLUT is active. Bit 7 has to be set to 1 to enable editing. When editing is enabled, the block number of a physical memory area can be written to the slot register address to map that area to the address in CPU address space. If editing is not enabled (bit 7 of $0000 is 0), the slot register addresses act as ordinary memory with no side effect.

ACT_LUT: These two bits specify which MLUT (0–3) is used to translate CPU bus address to system bus addresses.
EDIT_LUT: Selects which MLUT (0-3) will be edited.
EDIT_EN: If set (1), this bit enables MLUT editing, and memory addresses $0008–$000F (and $0002-$0003) will be used to edit the selected EDIT_LUT. If clear (0), those memory locations will be standard memory locations and will be mapped like the rest of slot 0.
IO_PAGE: Selects which IO page (0-3) is mapped to slot 6, when not disabled with IO_DISABLE.
IO_DISABLE: If set (1), slot 6 ($C000-$DFFF) is mapped through the active MLUT as normal. If clear (0), slot 6 is mapped to the selected IO_PAGE.
Note that writing a simple page number to register $0001 easily selects that IO page (including 0) to be visible, although there are also other Core2x entries now as well.
Core2x MMU Registers
SRAM_EN: Enables access to the SRAM pages 1-3 in 24-bit addresses 20:0000, 40:0000, and 60:0000, respectively.
IO_PAGE_EXT: Bit 2 of the total IO page number, enabling pages 4 and 5.
MOVE_IO: Moves IO pages from MMU access to 24-bit address F0:0000.
MOVE_FLASH: Moves Flash & Cart addressing from MMU access to 24-bit address 08:0000.
SPR_SEL: Select current Sprite Block in IO Page 0. 0 = Sprite 0-63, 1 = Sprite 64-127.
