碩呈 TRITAN TR4P133AT_AF
? MCU Operating voltage: 1.8V to 3.6V
? MCU Operation frequency:
(a) Use Internal 32MHz RC OSC : MCU run at 0.25MIPS/1 MIPS /2 MIPS /4 MIPS
(b) Use External XTOSC: MCU run at 0.5 MIPS (1MHz x’tal) ~8 MIPS (16MHz x’tal ).
? Memory Size
? Program ROM size: 2KX12 bits (OTP type)
SRAM size: 32x4 bits
? Wake up function for power-down mode
? HALT mode wake up source: RTC timer overflow or PA0~3, PB0~3, PD0~3 and PC0~PC1 edge trigger.
? Provided 12 input /output pins: each I/O has bit programmable as input or output port, these 12 I/Os
also provided edge trigger wake up function and pull up resistors configured by registers.
(a) They are provided with high sink current 20mA @VDD=3V, VOL=0.5V.
(b) They are provided with drive current 7mA @VDD=3V, VOH=2.5V.
(c) Pull up 150k ohm resistor.
? Provided 1 input pin (PA3), shared with RESETB/VPP pin by option, pull up 150k ohm resistor and edge
trigger wake up function.
? Provided 1 input pin (PC1), with pull up 150k ohm resistor and edge trigger wake up function.
? One 8 bits timer, clock source of timer is F MCK /8192( or 4096,2048,1024 ), the content of timer can be
cleared and read by program, it can be used as RTC timer when 32K X’tal oscillator mode is enabled.
? Oscillator type by option
(a) External X’tal oscillator 1~16MHz or 32KHz (external ceramic resonator or crystal oscillator, the pin
of X’tal is shared with PB0 and PB1 pin )
(b) Built-in internal RC OSC 32 MHz ----
frequency deviation within ± 2%, VDD=1.8V~3.6V, temp= -20 ºC ~70 ºC
? Four reset condition
? Low voltage reset (LVR=1.55V)
? Power on RC-reset
? External reset (RSTB) pin shared with PA3 by option.
? Watch dog timer overflow reset ( WDT period is 0.524 Sec~4.192 Sec, if MCU run at 4MIPS )
