The TR4P153BT/BF series are high-performance 4-bit RISC micro-controller embedded with 2KX12 bits OTP, 256X4 bits SRAM, 8 bit PWM, 11 Input/Output ports and one input port.（）
1、Operating voltage: (1) 2.0V to 5.5V for Temp. = 25℃ (2) 2.2V to 5.5V for Temp. = -40℃~+85℃
2、These MCU can operate in high speed. Oscillator type can be selected by option setting. High speed and low speed operating mode is selectable by software. Below is the chip performance in different modes.
3、Memory Size ：Program ROM size : 2KX12 bits (OTP type)； SRAM size: total 256x4 bits SRAM
4、Wake up function for power-down mode
5、11 input /output ports: PA0~PA2, PB0~PB3, PD0~PD3. Each I/O can be bit programmable as input or output port. These 11 I/Os also provided level-change-wakeup function. Pull up and pull down resistor setting is available by software.
6、1 input port PA3, PA3 is shared with RSTB (reset) pin by option. It also provides level-change-wakeup function. Pull up and pull down resistor can be configured by software too.
7、Port A, Port B and Port D are provided with high sink current 24mA @VDD=5V,Vol=0.5V( except PA3 )
8、Port A, Port B and Port D are provided with high drive current 23mA @ VDD=5V,Voh=4.5V( except PA3 )
9、PA1 built-in 38KHz modulator by option.
10、One Op-Amp is provided, three pins shared with PD0, PD1, PB2 (by option).
11、One comparator is provided, two input pins shared with PD2, PD3 (by option).
13、Four reset condition
14、Three internal interrupt sources: TIMER1, TIMER2 or RTC interrupt.
15、WDT(Watch dog timer)
16、Provides 8 Bits PWM, PWM signal output is shared with PA2 pin by option.
17、 Built-in external X’tal oscillator ( EXTOSC, use 1MHz~16MHz external ceramic resonator or crystal oscillator ). These two crystal pins are shared with PB1 and PB0 by option.
18、 Built-in high frequency internal 32MHz RC oscillator ( HRCOSC, frequency deviation within ±2 %, temperature range at -40℃~+85℃, Vdd = 2.0V to 5.5V )
19、Built-in low frequency internal RC OSC (LRCOSC) 459KHz ( frequency deviation within ±12%
