Hitachi HD4043312S 4-bit hmcs400-series microcomputer with large-capacity memory Datasheet

HD404339 Series
Rev. 7.0
Sept. 1999
Description
The HD404339 Series is 4-bit HMCS400-Series microcomputer with large-capacity memory designed to
increase program productivity. Each microcomputer has an A/D converter, input capture timer, and a 32kHz oscillator circuit for clock use all built in. They also come with high-voltage I/O pins that can directly
drive a fluorescent display.
The HD404339 Series includes six chips: the HD404339 with 16-kword ROM; the HD4043312 with 12kword ROM; the HD404338 with 8-kword ROM; the HD404336 with 6-kword ROM; the HD404334 with
4-kword ROM; the HD4074339 with 16-kword PROM.
The HD4074339 is a PROM version ZTAT microcomputer. Programs can be written to the PROM by a
PROM writer, which can dramatically shorten system development periods and smooth the process from
debugging to mass production. (The PROM program specifications are the same as for the 27256.)
ZTAT: Zero Turn Around Time ZTAT is a trademark of Hitachi Ltd.

In stop mode, the system oscillator is stopped. To ensure a proper oscillation stabilization period of at least
tRC when clearing stop mode, execute the cancellation according to the timing chart in figure 12.
In watch and subactive modes, a timer A or INT0 interrupt can be accepted during the interrupt frame
period T (see figure 13).
Note: In watch and subactive modes, an interrupt will not be properly detected if the INT0 high or low
level period is shorter than the interrupt frame period T. Thus, when operating in watch and
subactive modes, maintain the INT0 high or low level period longer than period T to ensure
interrupt detection.

The MCU automatically provides an oscillation stabilization period tRC when operation switches from
watch mode to active mode. The interrupt frame period T and one of three values for t RC can be selected
with the miscellaneous register (MIS: $00C), as listed in figure 14.
Operation can switch directly from subactive mode to active mode, as illustrated in figure 15. In this case,
the transition time TD obeys the following relationship.

MCU Operation Sequence: The MCU operation flow is shown in figures 16 and 17. RESET input is
asynchronous, and causes an immediate transition to the reset state from any MPU operation state.
The low-power mode operation sequence is shown in figure 17. With the IE flag cleared and an interrupt
flag set together with its interrupt mask cleared, if a STOP/SBY instruction is executed, the instruction is
cancelled (regarded as an NOP) and the following instruction is executed. Before executing a STOP/SBY
instruction, make sure all interrupt flags are cleared or all interrupts are masked.

Oscillator Circuit
Figure 18 shows a block diagram of the clock generation circuit. The system clock frequency of the
oscillator connected to OSC1 and OSC2 can be selected by system clock selection registers 1 and 2 (SSR1,
2: $027, $028) as shown in figures 20 and 21.
The system clock division ratio can be set by software to be 1/4, 1/8, 1/16, or 1/32. The subsystem clock
division ratio can be set by software to be 1/4 or 1/8.

manufacturer to determine the circuit parameters.
2. Wiring among OSC1, OSC 2, X1, X2 and elements should be as short as possible, and must not
cross other wiring (see figure 19).
3. When a 32.768-kHz crystal oscillator is not used, fix pin X1 to GND and leave pin X2 open.

I/O Ports
The MCU has 53 input/output pins (D0–D13, R00–R9 3) and one input-only pin (RA1).
• The 30 pins consisting of ports D0–D13, R1, R2, R8, and R9 are all high-voltage I/O pins. RA1 is a highvoltage input-only pin. The high-voltage pins can be equipped with or without pull-down resistance, as
selected by the mask option.
• All standard voltage output pins are CMOS output pins. However, the R0 2/SO pin can be programmed
for NMOS open-drain output.
• In stop mode, input/output pins go to the high-impedance state.
• All standard voltage input/output pins have pull-up MOS built in, which can be individually turned on
or off by software (Table 5).
Pull-up MOS on/off settings can be made independently of settings as on-chip supporting module pins.

The MCU has three built-in timers A, B, and C. The functions of each timer are listed in table 7.
Timer A
Timer A is an 8-bit free-running timer that can also be used as a clock time-base with a 32.768-kHz
subsystem oscillator. Timer A has the following features:
• One of eight internal clocks can be selected from prescaler S according to the setting of timer mode
register A (TMA: $008)
• In time-base mode, one of five internal clocks can be selected from prescaler W according to the setting
of timer mode register A
• An interrupt request can be generated when timer counter A (TCA) overflows
• Input clock frequency must not be modified during timer A operation

Notes on Use
When using the timer output as PWM output, note the following point. From the update of the timer write
register until the occurrence of the overflow interrupt, the PWM output differs from the period and duty
settings, as shown in table 8. The PWM output should therefore not be used until after the overflow
interrupt following the update of the timer write register. After the overflow, the PWM output will have the
set period and duty cycle.

A/D Converter
The MCU also contains a built-in A/D converter that uses a sequential comparison method with a
resistance ladder. It can perform digital conversion of twelve analog inputs with 8-bit resolution. The
following describes the A/D converter.
• A/D mode register 1 (AMR1: $019) is used to select digital or analog ports
• A/D mode register 2 (AMR2: $01A) is used to set the A/D conversion speed and to select digital or
analog ports
• The A/D channel register (ACR: $016) is used to select an analog input channel
• A/D conversion is started by setting the A/D start flag (ADSF: $020, 2) to 1. After the conversion is
completed, converted data is stored in the A/D data register, and at the same time the A/D start flag is
cleared to 0.
• By setting the IAD off flag (IAOF: $021, 2) to 1, the current flowing through the resistance ladder can be
cut off even while operating in standby or active mode
• The A/D data register is a read-only register consisting of a lower 4 bits and upper 4 bits (ADRL: $017,
ADRU: $018). This register is not cleared by a reset. Data reads during A/D conversion are not
guaranteed. After A/D conversion ends, the resultant 8-bit data is set in this register and held until the
start of the next conversion (figures 51 to 53).

Notes on Usage
• Use the SEM or SEMD instruction for writing to the A/D start flag (ADSF)
• Do not write to the A/D start flag during A/D conversion
• Data in the A/D data register during A/D conversion is undefined
• Since the operation of the A/D converter is based on the clock from the system oscillator, the A/D
converter does not operate in stop, watch, or subactive mode. In addition, to save power while in these
modes, all current flowing through the converter’s resistance ladder is cut off.
• If the power supply for the A/D converter is to be different from VCC, connect a 0.1-µF bypass capacitor
between the AVCC and AVSS pins. (However, this is not necessary when the AVCC pin is directly
connected to the VCC pin.)
• The port data register (PDR) is initialized to 1 by an MCU reset. At this time, if pull-up MOS is selected
as active by bit 3 of the miscellaneous register (MIS3), the port will be pulled up to VCC. When using a
shared R port/analog input pin as an input pin, clear PDR to 0. Otherwise, if pull-up MOS is selected by
MIS3 and PDR is set to 1, a pin selected by bit 1 of the A/D mode registr as an analog pin will remain
pulled up.

Between the VCC and GND lines, connect capacitors designed for use in ordinary power supply circuits.
An example connection is described in figure 54.
No resistors can be inserted in series in the power supply circuit, so the capacitors should be connected in
parallel. The capacitors are a large capacitance C1 and a small capacitance C2.

Notes: 1. When using the subsystem oscillator (32.768 kHz), one of the following relationships for f OSC
must be applied.
0.4 MHz ≤ fOSC ≤ 1.0 MHz or 1.6 MHz ≤ fOSC ≤ 4.5 MHz
The operating range for fOSC can be set with bit 1 of system selection register 1 (SSR1: $027).
2. The oscillation stabilization time is the period required for the oscillator to stabilize in the
following situations:
72
HD404339 Series
3.
4.
5.
6.
7.
8.
a. After V CC reaches 4.0 V at power-on.
b. After RESET input goes low when stop mode is cancelled.
c. After STOPC input goes low when stop mode is cancelled.
To ensure the oscillation stabilization time at power-on or when stop mode is cancelled, RESET
or STOPC must be input for at least a duration of t RC.
When using a crystal or ceramic oscillator, consult with the manufacturer to determine what
stabilization time is required, since it will depend on the circuit constants and stray capacitance.

Notes on ROM Out
Please pay attention to the following items regarding ROM out.
On ROM out, fill the ROM area indicated below with 1s to create the same data size for the HD404334 and
HD404336 as an 8-kword version (HD404338), and to create the same data size for the HD4043312 as a
16-kword version (HD404339).
The 8-kword and 16-kword data sizes are required to change ROM data to mask manufacturing data since
the program used is for an 8-k or 16-kword version.
This limitation applies when using an EPROM or a data base.
