UPD179F11x, UPD179F12x

Key Features:

Operating voltage: VDD = 1.8 to 3.6 V
Use this product in a voltage range of 1.9 to 3.6 V because the detection voltage (VPOC) of the power-on-clear (POC) circuit is 1.8 V±0.1 V.
Max. frequency: 4 MHz
ROM capacities: 4 KB to 32 KB flash memory
RAM capacities: 512 bytes to 1 KB
30-pin and 38-pin plastic SSOP package
78K0 CPU core
High speed (1 μs: VDD = 1.8 to 3.6 V, high-speed system clock: @ fXH = 2 or 4 MHz operation, 0.5 μs: VDD = 2.0 to 3.6 V, high-speed system clock: @ fXH = 4 MHz operation)
General-purpose register: 8 bits x 32 registers (8 bits x 8 registers x 4 banks)
On-chip single-power-supply flash memory
Self-programming (with boot swap function)
On-chip debug function
On-chip power-on-clear (POC) circuit and low-voltage detector (LVI)
On-chip watchdog timer (operable with the on-chip internal low-speed oscillation clock)
