General Description
The HT48R10A-1/HT48C10-1 are 8-bit high perfor-
mance, RISC architecture microcontroller devices spe-
cifically designed for multiple I/O control product
applications. The mask version HT48C10-1 is fully pin
and functionally compatible with the OTP version
HT48R10A-1 device.

The advantages of low power consumption, I/O flexibil-
ity, timer functions, oscillator options, HALT and
wake-up functions, watchdog timer, buzzer driver, as
well as low cost, enhance the versatility of these devices
to suit a wide range of application possibilities such as
industrial control, consumer products, subsystem con-
trollers, etc.

HT48R10A-1/HT48C10-1
Pin Description
Pin Name I/O Options
Description
PA0~PA7
Pull-high* Bidirectional 8-bit input/output port. Each bit can be configured as wake-up input
I/O
Wake-up
CMOS/Schmitt
by options. Software instructions determine the CMOS output or Schmitt trigger
or CMOS (dependent on options) input with a pull-high resistor (determined by
trigger Input pull-high options).
PB0/BZ
PB1/BZ
PB2~PB7
Bidirectional 8-bit input/output port. Software instructions determine the CMOS
output or Schmitt trigger input with a pull-high resistor (determined by pull-high
I/O
Pull-high*
I/O or BZ/BZ
options).
The PB0 and PB1 are pin-shared with the BZ and BZ, respectively. Once the PB0
and PB1 are selected as buzzer driving outputs, the output signals come from an
internal PFD generator (shared with timer/event counter).
VSS
¾ ¾ Negative power supply, ground
PC0/INT
PC1/TMR
PC2
I/O
Pull-high*
Bidirectional I/O lines. Software instructions determine the CMOS output or
Schmitt trigger input with a pull-high resistor (determined by pull-high options).
The external interrupt and timer input are pin-shared with the PC0 and PC1, re-
spectively. The external interrupt input is activated on a high to low transition.
RES
I ¾ Schmitt trigger reset input. Active low
VDD
¾ ¾ Positive power supply
OSC1/PC3
OSC2/PC4
OSC1, OSC2 are connected to an RC network or Crystal (determined by options)
for the internal system clock. In the case of RC operation, OSC2 is the output ter-
I
O
Crystal or RC
or Int. RC+I/O
or Int. RC+RTC
minal for 1/4 system clock. These two pins also can be optioned as an RTC oscil-
lator (32768Hz) or I/O lines. In these two cases, the system clock comes from an
internal RC oscillator whose frequency has 4 options (3.2MHz, 1.6MHz, 800kHz,
400kHz). If the I/O option is selected, the pull-high options also be enabled. Oth-
erwise the PC3 and PC4 are used as internal registers (pull-high resistors always
disabled).
* The pull-high resistors of each I/O port (PA, PB, PC) are controlled by an option bit.
Absolute Maximum Ratings
Supply Voltage ...........................VSS-0.3V to VSS+6.0V
Input Voltage..............................VSS-0.3V to VDD+0.3V
www.DataSheet.net/
Storage Temperature ............................-50°C to 125°C
Operating Temperature...........................-40°C to 85°C
Note: These are stress ratings only. Stresses exceeding the range specified under ²Absolute Maximum Ratings² may
cause substantial damage to the device. Functional operation of this device at other conditions beyond those
listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliabil-
ity.
