M37733S4LHP
16-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37733S4LHP is a microcomputer using the 7700 Family core.
This microcomputer has a CPU and a bus interface unit. The CPU is
a 16-bit parallel processor that can be an 8-bit parallel processor,
and the bus interface unit enhances the memory access efficiency to
execute instructions fast. This microcomputer also includes a 32 kHz
oscillation circuit, in addition to the RAM, multiple-function timers,
serial I/O, A-D converter, and so on.
Its strong points are the low power dissipation, the low supply voltage
and the small package.

16-BIT CMOS MICROCOMPUTER
BASIC FUNCTION BLOCKS
The M37733S4LHP has the same functions as the
M37733MHBXXXFP except for the following :
(1) The memory map is different.
(2) The processor mode is different.
(3) The reset circuit is different.
(4) Pulse output port mode of timer A is available.
(5) The function of ROM area modification is not available.
MEMORY
The memory map is shown in Figure 1. The address space has a
capacity of 16 Mbytes and is allocated to addresses from 016 to
FFFFFF16. The address space is divided by 64-Kbyte unit called bank.
The banks are numbered from 016 to FF16.
Built-in RAM and control registers for internal peripheral devices are
assigned to bank 016.
Addresses FFD616 to FFFF16 are the RESET and interrupt vector
addresses and contain the interrupt vectors. Use ROM for memory
of this address.
The 2048-byte area allocated to addresses from 8016 to 87F16 is the
built-in RAM. In addition to storing data, the RAM is used as stack
during a subroutine call or interrupts.
Peripheral devices such as I/O ports, A-D converter, serial I/O, timer,
and interrupt control registers are allocated to addresses from 016 to
7F16.
A 256-byte direct page area can be allocated anywhere in bank 016
by using the direct page register (DPR). In the direct page addressing
mode, the memory in the direct page area can be accessed with two
words. Hence program steps can be reduced.

in the microprocessor mode. In the microprocessor mode, signal E can also be fixed to “H” when the internal
memory area is accessed.
